Hospital UPS runtime: how to calculate, test and maintain it

Hospital UPS runtime is not a fixed figure on a specification sheet. It depends on the measured critical load, battery condition and temperature, UPS efficiency, and the time needed for the alternative supply to take over. This article explains how to turn those factors into a defensible estimate and verify it through a planned, traceable test.

It covers clinical operating scenarios, manufacturer discharge curves, variation between battery blocks, coordination with the generator and safe end criteria. It also sets out the data to record during acceptance and the trends to monitor throughout the battery bank’s life. The aim is to demonstrate useful operating time under the site’s defined electrical and clinical conditions without disrupting care or unnecessarily shortening battery life.

Medical isolation transformers: how to size them and verify thermal performance

Selecting a medical isolation transformer takes more than adding up equipment nameplate ratings. This article explains how to turn a clinical equipment inventory into realistic load scenarios, assess simultaneous demand, inrush currents, impedance, selectivity and planned expansion, and verify that the panel retains adequate thermal headroom under actual operating conditions. It also covers commissioning measurements, thermal imaging interpretation and the evidence maintenance teams need to retain. A practical design matrix, guidance on integrating single-phase and three-phase solutions, common mistakes and a step-by-step verification plan connect the calculations to the installed system. The aim is a coordinated, maintainable medical IT installation that can accommodate future changes without arbitrary oversizing or compromising continuity of patient care in operating theatres and critical areas.

The importance of investing in uninterruptible power supply systems

Uninterruptible Power Supply Systems (UPS) in hospitals guarantee the continuity of energy.

Uninterruptible Power Supply Systems (UPS) have emerged as essential components in the infrastructure of various sectors, highlighting their crucial role in critical environments such as hospitals. That is why it is so important to invest in renewing and acquiring new UPS systems for healthcare centers.

Electrical outages and voltage alterations are more frequent than desirable, and during that time the devices cannot stop working.

Batteries and emergency power supply units in hospitals: what you need to know

For decades, the implementation of technology in the different spheres of human life has transformed the way we consume, relate to each other and live. It has certainly transformed it for the better. After all, a priori, technology makes our lives easier. However, as we use more and more electronic systems in our daily lives, we also become more energy dependent.

That is why, in a field such as healthcare, the use of batteries for emergency supply units in hospitals is essential to guarantee permanent access to the power supply, even in the most complicated situations or in exceptional events that may cause, for example, power cuts.

Today we want to address the importance of batteries and uninterruptible power supplies (UPS) for the proper functioning of the healthcare system.

Alarm repeaters

Current alarm repeaters, in addition to their basic and logical use, which is to ‘snitch’ about an error or possible problem situation, have evolved to help medical personnel act. And it is that health workers have often considered this alarm as a necessary ‘nuisance’, seeing its required maintenance as a nuisance.

The fact is that, with some frequency, medical personnel have not known how to act in the face of these alarms. Or they simply did not know the risk situation that was taking place, especially in the alarms related to electrical safety.

But today, alarm repeaters not only provide additional information to medical personnel, but indicate what to do at all times to remedy the situation, or who to call. With them, touch screens also stand out on technical panels, for example in operating rooms, which allows the graphic display of the alarm with icons and colors.

8 ETKHO solutions for electrical safety in operating rooms

Electrical safety in medical centers, especially in critical hospital areas, is a matter that must be considered with the utmost seriousness.

Having a well-designed and complete electrical system is equivalent to taking all possible precautions beforehand and, therefore, facing the potential complications related to hospital electrical safety.

Not surprisingly, hospital units are contexts with high risks of electrical failures if they do not have an adequate electrical safety system. We are talking about failures that are not only limited to material equipment, but can cause damage and human loss.

At ETKHO, as experts in hospital electrical safety, we are specialized in the manufacture of electrical safety equipment and services for hospitals and operating rooms.

Automatic switching systems

These devices are crucial for the proper functioning of the electrical network in hospital areas, especially when faults may arise.

In recent times, the continuity of service in low voltage electrical installations has become essential. Especially in the hospital setting. This requirement is essential to create facilities that, economically and functionally, are efficient.

The reason? The reduction to the minimum of the problems derived from electrical failures thanks to a system that, automatically, is capable of switching the power supply from the main line to an emergency one.

Automatic switching incorporates sequences that automatically control system components without operator intervention.

Isolation transformers for medical use

Medical-grade electrical transformers prevent system failures and protect patients and healthcare personnel from electrical shock.

Circuits that cannot withstand direct current load need protection. The isolation transformer provides that protection, increasing or declining the alternating currents before they reach the main equipment to which it is connected.

Therefore, isolation transformers separate a part of an electrical circuit from the main powers, guaranteeing the proper functioning of the unit. We are talking about transformers that are similar to any other type, but found in applications that have sensitive circuits.

The transformers for clinical use are manufactured to guarantee the maximum safety of hospital patients, managing to isolate the external electrical supply from the power supply of the different elements and machines used in medicine.

Hospital ground panels and electrical outlets: what they are, what they are for and benefits

In hospitals and health centers, each machine has its mission or objective. In the case of hospital ground panels and electrical outlets, they help prevent and avoid contact voltages within critical medical areas. The possibility of electrical shocks caused by poor equipment grounding is one of the great risks faced by patients and healthcare personnel.

For this reason, it is essential to have adequate health technology, especially with the devices that guarantee the perfect functioning of electromedicine.

Hospital earth panels and electrical outlets are essential to help prevent contact voltages within hospitals and, especially, in operating rooms, ICUs or, in general, critical hospital areas.

Motor arm systems for critical areas and operating rooms

The main objective of tools for the health sector is usually to facilitate the work of doctors and the medical team and, of course, reduce human error. In this sense, an example of technology in hospitals are motor arm systems, especially in critical areas and operating rooms.

One of the most common medical instruments in hospitals are motor arm systems or articulated arm systems, whose advantages and benefits are multiple.

This system is an instrument made with innovative technology to facilitate surgical interventions and, at the same time, help in the recovery and well-being process of patients who have undergone surgery.
