DC Hipot Testers DPW Series
Model : DPW-60-5 DPW-80-5 DPW-120-5 DPW-160-2 DPW-200-5
These portable testers have been designed to be used in testing high voltage equipment in power engineering. Routine testing of the insulation and leakage is a necessary requirement for surge arresters, cable breakdown testing, capacitor charging and other laboratory use.
Machine Feature
• Switched-mode technology utilizing pulse width modulation to control the output voltage accurately.
• Voltage divider is an integral part of the tester with an surge limiting resistor.
• Tester delivered in two sections: Control and HV unit. Each packed in a flight case for easy transportation.
• Testers of over 200kV voltage, HV unit has adjustable legs to increase the equipment’s stability.
• Digital kilo voltmeter and µA/mA meters display the test voltage and leakage current.
• Zero start up. Audible alarm and LEDs for breakdown and over voltage occurrences.
• Small dimension. Low weight. Carried conveniently.
• Discharge pole with limiting current impedance.
