Product introduction

Features:
JP series cabinet has 3 basic functions: power distribution, compensation and measurement. Clients can select from the following schemes:
01 - power distribution + compensation + measurement
02 - power distribution + compensation
03 - power distribution + measurement
04 - compensation + measurement
05 - power distribution
06 - measurement
07 - compensation

Performance:
1. Quick response, nice compensation effect, reliable operation, and optional function of earthing leakage protection
2. Protection function: overvoltage, overload, undervoltage, undercurrent, short circuit, loss of phase, and zero sequence ultra-limit
3. Automatic operation function: automatic recovery within 10s after power off and power on
4. Power factor of the grid increasing to above 0.95

Operation Conditions:
1. Ambient temperature: -40℃～+55℃
2. Relative humidity: ≤90% (relative ambient temperature 20℃～25℃)
3. Altitude: ≤3000m
4. Installed in the cabinet; no potential of fire hazard or explosion; no severe pollution, chemical corrosion or severe vibration
