Facts about medical technology

The standard IEC 60601-1 and the EU guideline 93/42/EWG define the safety of electrical systems. To guarantee a safe power supply, experience and knowledge is necessary. REO has many years experience of transformer production for industrial applications, REO provides solutions which go above and beyond the required standards

REO transformers are especially characterized by:

Minimal leakage field – Meaning that high Electro-magnetic compatibility (EMC) can be guaranteed
High quality core – Means high efficiency and good ON/OFF load regulation properties
Fully encapsulated – For protection from environmental influences and improved heat dissipation
Filter, overvoltage protection and inrush current limiting sections are developed and
manufactured in-house, which ensures optimal performance.

REOMED I Isolating transformer – ed 3.1

Medical systems must reliably comply with the leakage currents required by the applicable standard – if several devices are connected together, the total leakage current increases accordingly. The TÜV-tested REOMED I isolating transformers are tried and tested devices for use in all electrical systems in medical rooms. They limit the leakage current and thus help to ensure patient safety. In addition to very good efficiency and simple wiring, REOMED I isolating transformers are characterised by a very low stray magnetic field and high safety. In addition to the standard series, the transformers can of course also be individually produced according to customer specifications and extended with electronic switch-on attenuation, overvoltage protection and a mains filter.

REOMED II Isolating transformer – ed 3.1

The REOMED II Isolating transformer provides reliable leakage current reduction in medical applications. Safe isolation on the input side is effected by using high quality materials and first class production methods. The isolating transformers are designed for low internal losses and so achieve very low no-load losses (≤ 1% relating to the input power). Overload and short-circuit protection on the input and output side is effected by an integral circuit breaker. The transformer is isolated using an illuminated mains switch and circuit protection is effected by two fuses on the input side and a single-pole one on the output side. As thermal protection is utilized problems regarding fuses (i.e incorrect values being fitted, power interruption are avoided) Furthermore, a temperature cut-out is integrated in the isolating transformer, which provides an additional protection in the event of exceptional ambient conditions or prolonged obstruction of the cooling vents.

Equipment: REOMED ISOMONITOR

Standard safety devices used for protection against isolation failures, such as residual-current devices (RCD) used in domestic installations, cannot detect isolation breakdown on the secondary side of isolating transformers. The ISOMONITOR monitors the dielectric resistance between both of the live output- socket terminals of the isolating transformer and earth potential, and generates a warning signal in the event of a fault condition. The insulation resistance is constantly monitored to ensure that it does not drop below a limit of 50 kOhm (25 kOhm). If it does fall below this value, then both an acoustic alarm (sound pulsating at approximately 3kHz and 98 db) and a visual signal (LED display) are generated. The ISOMONITOR can be connected to one of the socket outlets of the isolating transformer. Further functional options are monitoring of the temperature of the transformer including audible and visual alarm, as well as a visual display of the transformers power consumption.

Errors can be reset using the appropriate button on the ISOMONITOR, the visual alarm is automatically reset as soon as the error is detected and resolved.
