Medical isolation transformers

Medical isolation transformers with insulation monitoring system and the temperature of the Russian production to supply equipment of all health facilities in Group 2.

Isolating transformers series TP and TRT (index M) designed to supply medical areas of two. Transformers perform the conversion networks with earthed neutral in the network with isolated neutral (IT Network). At the same time, in accordance with the requirements of GOST 50571.28 and instructions RTM 42-2-80, transformers continuously monitors the insulation resistance of the network, the temperature of the windings and the value of the connected load.  

Isolating transformers series TP and TRT (index M) is used to reduce the risk of accidental contact with the staff or the patient to live parts of equipment or dead parts, find themselves under stress (in the case of damage to the insulation.) The use of medical isolation transformer and network with isolated neutral does not allow in this situation, the emergence of the current string and electric shock to persons. This allows you to continue the operation and use operational equipment (including life support systems) without endangering the life and health of the patient and the staff even in emergency situations. The product is a complete panel construction with isolation transformers (with earthed screen between primary and secondary windings) system, inrush current limiting, automatic protection at input and output, control system insulation, temperature and load current. The product has an output for connection of the remote control transformer MAC. Also equipped with a transformer output for integration into the SCADA system of medical institutions (of the "Intelligent Hospital"). All medical isolation transformers are certified to GOST 50571.28 ("Requirements for special installations, electrical medical areas") and GOST 30030-93 ("Transformers separating and safe separating transformers") and comply with all requirements of the RTM instructions 42-2-80.

(For regular customers a discount system) Protection and control:

1. Automatic protection of input and output. Provide overcurrent protection.

2. Temperature control system transformer. Provides a signal of overheating transformer to the post of Remote Control (MAC) and a red LED on the front panel of the product, "EMERGENCY".

3. The control system continuously monitors the operating current value of the load current in phases, with the post of MPC displays the value of the current transformer load as a percentage of par. In case of exceeding the nominal control system gives an alarm for the post of MPC and a red LED on the front panel of the product, "EMERGENCY".

4. System inrush current limit provides an isolation transformer inrush current at startup.

5. Insulation monitoring system continuously monitors the network load in order to control the state of isolation IT — network. In the case of reducing the isolation below a set level (50kW) emits a signal "insulation fault" on Macs and a red LED on the front panel of the product ACCIDENT.http://ocdk.ru/med

Post Remote Control MPC. In most cases, isolation transformers are equipped with MPC — Remote control fasting isolating transformers. MPC is a unit of light, sound alarm and monitoring of network isolation, as well as temperature control isolation transformer. Has an LED load control. MPC is installed directly in the area of personnel and has a degree of protection IP 54. To one medical transformer can connect up to 6 of the remote control. At serviceable network isolation green light "isolation normally." In case the insulation resistance below the value (for example, less than 50 ohms) goes out and the green indicator lights up in red "violation of isolation," is heard at the same time an intermittent beep (off-click the "Sound"). If overheating isolating transformer (temperature over 80 ° C), the red LED "Overheated transformer" and you will hear an intermittent beep. Button "TEST" and "RESET" are used to periodically check the system control isolation.
