Power Conditioner

Medical-Grade Power Conditioners:

Power conditioners are devices used to provide pure, refined, and steady streams of A.C. supply. They prevent the sagging, spiking, or swelling of electricity and simultaneously minimize electrical noise. They are used as safeguards for most of the electrical equipment and boost their performance to a great extent.

Medical-Grade Power Conditioners are essential components of specific hospital electrical devices, which include medical imaging, among others. They also act as barriers against unplanned hospital supply outages.

This article will explore a few critical characteristics of medical-grade power conditioners, including their indications and how they work.

Indications to Use

There are various uses for the device in hospital settings:

Averting Outages: To most of us, the loss of electricity is a momentary annoyance. At a hospital, however, sudden supply outages can result in various life-threatening disturbances. Numerous events with links to catastrophic loss of life in hospital settings are caused by it. For example, patients who rely on Oxygen concentrators to maintain adequate levels of Oxygen might experience severe shortness of breath. Also, the ones that need regular dialyzes might be endangered since the machines will grind to a halt. The failure of critical care apparatus prompted the evacuation of hospitals, i.e., intubated patients had to be shifted to another health care facility for fear of respiratory collapse. A power conditioner puts a stop to sudden power loss and prevents dire situations.

Getting Rid of Surges: Often, a surge can damage precious, expensive machinery. Since they promptly buffer unwanted swells, they save the hospital management plenty of money. In hospitals, the second most crucial goal is the protection of critical health care apparatus. The first one, of course, being patient safety.

Saving Medical Information Systems: With the advancement of technology, institutions have started leaning more and more on electronic databases; hospitals are no exception. The patient monitoring devices and medical information systems have only gotten more remarkable with time. Old, larger semiconductor chips are being replaced with faster, smaller ones. This decrease in size has left them more open to destruction by the lousy electricity quality. These power conditioners allow medical equipment to function efficiently and in a reliable way by minimizing the frequency and amplitude of electronic transients.

Reducing Lines Noise: Hospitals should be places of rest and solitude. Noisy environments are often unbearable to severely ill patients. Hospital-grade power conditioners eliminate loud hum and help maintain a peaceful atmosphere.

Imaging Equipment: One of the most important diagnostic tools is imaging equipment, like C.T. or MRI scanners, and more. Any defect in them can create incorrect diagnoses. The quality of electricity delivered to medical equipment has a direct impact on the reliability and validity of these tools. They also decrease any distortions caused by sudden surges in power through the circuits of this imaging gadgetry.


Not many complications can arise from medical-grade power conditioners. In some cases, they might get overheated. They have a lifespan of about thirty years, and without replacement after this period, they might explode.

Sometimes, an imbalance in the supply between various levels might be found. Central control is needed, which can be complicating for some people. Sometimes, a massive loss of conduction can happen.

Alternative Instruments:

UPS configuration:

A UPS can act as an alternative to the power conditioner for usage in a medical setting. It is practically used to charge the battery. It uses an inverter to convert D.C. to A.C. and transfer it to loads. The battery is an alternate source of energy as well. It is a standard solution used everywhere. During load shedding, mains failure, or when there is a shortage of electricity, UPS serves as an ideal source for running loads to provide uninterrupted supply. This acts as a backup in emergency rooms, operation theaters, laboratories, and other sensitive diagnostic imaging apparatus in hospitals. Other important factors like its manageability, reliability, and running cost must be considered while developing UPS. Out of the two main configurations, either a centralized UPS configuration or Distributed UPS configuration is usually used in hospitals. Centralized UPS configuration is installed in the central acting electrical panel from where supply is transmitted across the hospital. Distributed UPS configuration, on the other hand, is usually introduced close to specific equipment like MRI or ICU. The important installation factor which can be used with the UPS power surges, which can control the output. Thus, UPS introduces an advanced level of protection to medical devices like line conditioners.

Surge Protectors:

They can protect against surges in the power conditioner. But unlike hospital-grade conditioners, they will not protect against a sudden drop in electricity or other related issues. So, power conditioners have an advantage over surge protectors.

General specifications:

A variety of medical-grade power conditioners exist depending on their function and size as per requirements. It ranges from providing limited voltage modulation to protecting as many as six supplies and current related issues. Similarly, the size range is also varied.

 Some specifications penned down to consider while searching:

Voltage handling: Small power conditioners voltages are mostly rated in volt-amperes (V.A). At the same time, larger ones in kilovolt-amperes (kV·A) use single-phase voltage as incorporated by Powervar.

Waveforms and frequency: Ideally, sine waveform is used with zero impedance, with frequencies ranging from 50 Hz, 60Hz, and 400 Hz.

Changing frequency: Basic specifications given by Power quality show that frequency values are changeable. (E.g.  60 Hz to 50 Hz converters).

LEDs indicators: visually displaying the working of system (red, green, yellow light)

Bypass switch: Permitting uninterrupted flow of energy.

Patient safety:

  1. Plugs and receptacles should be hospital-grade based on recommendations byLeapfrog Hospital Safety Grade.
  2. Class and group of power conditioners recommended by IEEE must be already defined.
  3. Usually, the internal infrastructure of the system is not touchable or freely accessible by the user.
  4. Designed to work only in the patient vicinity
  5. Passing voltage  less than 10 volts in normal mode and less than 0.5 volts in neutral-to-ground based on ANSI/IEEE C62.41
  6. The maximum leakage current level is maintained at 300 μA for patient protection.

How does it work?

As it is clear now, the power conditioner can control and improve the A.C. voltage. It also transmits only modulated voltage supply with the capacity to remove spikes, noise, frequency distortions, brownouts, and blackouts that can deteriorate or negatively influence the performance level of any device loaded. It conveys a voltage with a fixed and appropriate level so that the appliances attached can work efficiently without any break. Hence it can be said that it works as a link between your apparatus and the external energy supply. It smooths down the variations of energy and any electromagnetic obstruction which can damage your equipment. It receives the voltage, adjusts it, and transfers it to the connected equipment based on its prerequisites.  When voltage catches up to a specific limit, outraging the equipment capacity, the conditioner takes it away to the system's safety ground level. In this manner, it ensures the life of medical appliances and guarantees a more extended life. It provides only the needed amount of voltage with spike and noise constriction to guarantee the quality and consistency of sensitive diagnostic and laboratory apparatus.

While working with them, the following steps should be kept in mind to get maximum output from it. Introducing it closest to the equipment is beneficial. There is no need to use any extra surge protectors, extension cords, or any other filtering gadgets while working with it. Make sure that all equipment is shut down while connecting the conditioner into the A.C. source. Now, attach the equipment into the conditioner receptacles. Once the conditioner has been appropriately introduced, you can turn on your equipment.
