Product description
Product Introduction
Meets the relevant provisions of DL/T848.1-2004. Used for leakage current testing of zinc oxide arresters at DC 1mA voltage (U1mA) and 0.75U1mA, and for DC withstand voltage and leakage current testing of transformers, power cables and other electrical equipment.
Main Features
◆ High-frequency voltage multiplier rectification, pulse width modulation, low ripple factor;
◆ With overcurrent, overvoltage, and zero-position start protection functions;
◆ High output power, small size, stable performance;
◆ With 0.75 test function, convenient for measuring the leakage current of zinc oxide arrester at 0.75 times the voltage.
Technical Parameters
◆ Input voltage: AC220V, 50Hz ◆ Ripple factor: ≤1%
◆ Voltage accuracy: 1% ◆ Current accuracy: 1%
◆ Operating mode: intermittent use ◆ Rated load: 30 minutes
◆ Voltage, current measurement: 4 1/2 digit digital display
