Over-voltage protection relay PR200

under-voltagecurrentoverload

PR200 motor protection relay is an all-in-one solution designed to continuously monitor 3-phase power lines for abnormal conditions. It can use with motors less than 690V/820A. Packed inside a small and economic package you’ll find a solution designed to save you time and money. -. High accuracy sample calculation, class 0.5 for 2% -120% measurement range; class 1 for 120% -1000% measurement range. -. Built-in 2-channel relay, free to user set protected trip mode, alarm mode and trig mode. In protection mode, channel 1 relay can use for alarm, channel 2 for trig operation. -. User free to set each protection function act off, alarm or trip. -. Build in Sequence of Event function, can logger last 10 trip records. -. With programmable analog output function, user option RS-485 communication interface. -. Can provide basic electrical parameter for user SCADA system. -. Wide range of power supply AC85-265V or AC80-450V. Protection function Start Overtime, Over Load, Phase Failure, Stall, Current imbalance, Under load, Jam, Ground fault Working environment : Motor rated voltage: AC380V / AC660V Motor rated current: 0.5-820A Working temperature: -20C ~ +60C Storage temperature: -40C ~ +80C Relative humidity: < 93% RH Elevation: not more than 3000 m Atmospheric conditions: installation site does not allow the explosive medium, containing gas to corrode metal and damage the insulation and conductive medium. Measuring accuracy : Current: ± 0.5% (2% to 120% of Ie) ± 1% (120% to 10% of Ie) Voltage: ± 0.5% Leakage current: ± 1% (10% to 100% of Ir) Analog Output: ± 1% (4 ~ 20mA)
