Eltako NR12-001-3x230V network monitoring
Eltako NR12-001-3x230V network monitoring
Eltako1 changeover contact potential-free 10A/250V AC. Stand-by loss only 0.8 watts. Modular device for mounting on mounting rail DIN-EN 60715 TH35. 1 division unit = 18mm wide, 58mm deep. For monitoring 230V AC voltage between 1 to 3 external conductors and the neutral conductor and for monitoring the rotating field (clockwise) in the rotary switch positions 2Ph and 3Ph. In this position, only the rotating field is monitored, regardless of the mains voltage. Supply voltage L1-N 180-250V/50-60Hz. If L1 fails, the relay drops out immediately without a release delay. Two pick-up and release voltages can be set using the lower rotary switch on the front and the number of monitored external conductors must be specified. U1: 161V dropout voltage and 185V pick-up voltage; U2: 196V dropout voltage and 206V pick-up voltage according to VDE 0100, part 718 (formerly: VDE 0108, part 1). LED display for correct applied voltage. If the polarity is incorrect or there is a missing external conductor, the LED flashes quickly. RV off-delay can be adjusted from 0.1 to 8 seconds using the upper rotary switch. While the RV time is running, the LED flashes slowly. Start-up delay 0.5s. Maximum device fuse protection 16A
