Over Under Voltage & Overload Protection (Multimeter)
Digital Multimeter with Control relay to protect against one or all of the following problems:1-Over Under voltage.2-Phase rotation error3-phase lossIf one or more of these problems occur, the control relay disconnects the load / contactor to protect it and displays an alarm whether by its alarm LED or on its display.Features:--------------1) Over voltage (OV) threshold can be adjusted by the user from 105% to 120% of nominal voltage (220 VAC) .2) Under voltage (UV) threshold can be adjusted by the user from 95% to 70% of nominal voltage (220 VAC)3) Time of disconnecting the load after detection of OV / UV can be adjusted from 1 to 120 sec. .4) Time of reconnecting the load after detection of normal utility (no OV / UV) , can be adjusted from 1 to 120 sec.Specifications:1) Power supply: 380 / 220V AC.2) Ammeter: 0-6A3) Voltmeter: 85-280 VAC (phase-neutral) 145-467V AC (phase-phase)4) Frequency meter: 45-65Hz5) Connection type: 3phase6) Power Consumption:7) Current Transformer ration: 25-2, 500 / 5A8) Accuracy: 1% -1 digit [ (10% -100% ) x full scale]9) Display: red LED display10) Box material: nonflammable11) Operation range: -5oC + 50oC12) Protection class: IP 20 (for front panel)13) Standards: IEC 61010-1, IEC61000-6, IEC61000-4, IEC 62052 Class 2, type PR19 (96 x 96mm)14) Cable diameter (for terminal) : 2. 5mm215) Installation: flush-mounting16) Relay: 8A.17) Weight: 0. 3kg
