The two-part test sets PGK HB generate variable AC test voltages of mains frequency or DC voltages of positive or negative polarity.
The operating unit in 19“ design has a voltage and current display, safety control elements according to VDE 0104 and a variable transformer for voltage adjustment.
The high voltage unit contains an oil insulated high voltage transformer and, depending on the desired operation mode, a rectifier rod or a resistor rod. The polarity of the DC test voltage can be changed by reversing the rectifier in the high voltage unit.
Features:
absolutely maintenance-free design
stepless adjustable output voltage
safety control according to VDE 0104
short-circuit protected by internal current limitation
voltage indication: 2 range analogue meter, ratio 1:3
current measurement: 3 range analogue meter, decadic thermal overcurrent switch-off
