EM TEST vsurge NX20 Surge Generator
Description
vsurge NX20 Surge Generator for Solar Panel testing – 1.2/50µs as per IEC/EN 61730 up to 20 kV
EM TEST vsurge NX20 Surge Generator for Solar Panel testing is specifically designed to generate high voltage transients as required by IEC/EN 61730-2 for safety testing of photo voltaic panels.
The specified waveshape of 1.2/50us must be generated and maintained as specified across a broad range of capacitance the PV’s do represent. Such generator needs to be based on different pulse shaping networks to cope with the variable capacitive load of the panels depending on their size and design.
EM TEST vsurge NX20 covers the full range of capacitive load photovoltaic panels may represent offering 11 different load ranges. Each load range is based on a separate pulse forming network to comply with the tolerances given in the standard.
Features
- Surge voltage up to 20 kV
- 11 different capacitance ranges selectable from 20nF to 170nF
- Compliant to IEC/EN 61730-1/2
- Peak voltage and peak current measurement
- Automatic detection of selected load range and polarity
- Interlock and Warning lamp control
- Manual operation
- USB (optical link) and Ethernet interface
