BENDER VME420-D-2 RESIDUAL CURRENT MONITOR, bender vme420-d-2 Residual Current Monitor, 3-phase, 420V, 50/60Hz, digital display

• Undervoltage and overvoltage monitoring of AC/DC systems 0…300 V in the frequency range DC/15…460 Hz

• Preset function: Automatic response value setting for undervoltage and overvoltage, < U and > U as well as for underfrequency and overfrequency < f and > f.

• Voltage and frequency monitoring with window discriminator function, < U and > U as well as < f and > f.

• Indication of the system frequency f

• Start-up delay, response delay and delay on release

• Adjustable switching hysteresis for U and f

• r.m.s. value measurement AC + DC

• Measured value display via multi-functional LC display

• Alarm indication via LEDs (AL1, AL2) and changeover contacts (K1, K2)

• N/C operation or N/O operation selectable

• Password protection against unauthorised parameter changing

• Fault memory can be deactivated. In the "con“ mode, all alarm parameters remain stored on failure of the supply voltage.

• Start-up of the device with or without simulated alarm message

• Frequency alarm behaviour in case of measuring voltage failure can be parameterised
