Industry sectors such as Railways, substation, Marine are all subject to high voltages and harsh ambient conditions. Quite often the galvanic isolation under such harsh conditions is at risk leading to false measurements or it may even result in personal injury or damage to the equipment. These risks have to be eliminated safely and over the long term by suitably designed high-voltage isolators.

The VariTrans P 41000 high voltage isolators have been specially designed for measurements of bipolar voltages from millivolts to volts. They reliably isolate high potentials at the input circuit.

The isolating distances are designed to withstand permanent voltages up to 3600 V AC/DC and fast transients up to 20 kV. Protection against electric shock is achieved through 3 way galvanic isolation according to EN 61140 – between input and output and power supply

The high voltage isolator’s vacuum encapsulation provides maximum protection against aggressive environmental influences, shock and vibrations and ensures that the high disruptive strength required for working voltages up to 3600 V AC/DC is maintained over the long term.

The control cabinets often have space constraints. Our newly developed TransShield technology offers the solution to space restrictions. This technology allows very compact high voltage transformers with low leakage. Thanks to the resulting space advantage, the P 41000 high voltage isolators can be installed in an only 22.5 mm wide modular housing.

This high voltage isolator provides complete flexibility in selecting the input and output ranges – 16 input/output signal combinations can easily be selected with a rotary encoder switch on the front of the device. It comes with an integrated 20 to 253 V AC/DC VariPower broad-range power supply that ensures trouble-free operation with alternating or direct voltages everywhere in the world and provides maximum safety even in unstable power supply .
