Voltage Monitor Single Phase AC/DC CM-ESN , 30-500V, 24-240VAC/DC No Time Delay

Model : 1SVR 450 215 R 0200

Type

CM-ESN

Supply Voltage

24-240VAC/DC

Voltage measuring ranges : /-/ ; 30-300 V , 50-500V , no time delay

The voltage being monitored is applied to the terminals B1 or B2 or B3 and C. The unit can be set for 2 monitoring modes by a rotary switch on the front face.

The overvoltage mode (OV) means, if the monitored voltage is above the set point, the output relay will energize. The undervoltage mode (UV) means, if the monitored voltage is below the set point, the output relay will energize.

The output relay de-energizes when the monitored voltage is above or below the set hysteresis percentage. Without or with delay on operate 0.05...30 s. Hysteresis is adjustable from 5...30 %.

Measuring, output, and supply voltage circuits are electrically isolated to prevent mutual interference. As one measuring cycle takes only 80 ms, changes in voltage can quickly be detected.

-Monitors AC or DC voltages from 50 mV to 500V in 6 ranges

-Up to 3 measuring ranges in one unit

-Convertible to overvoltage or undervoltage monitoring (For supply voltage versions 24-240VAC/DC)

-Switching hysteresis adjustable from 5-30%

-With or without delay on operate 0.05-30s 2c/o contacts

-2 LEDs to indicate operational status
