LDRT Mains Restoration / Brown-Out Timer

  • Mains Restoration/Brown Out Timer – Delay On
  • Single voltage
  • Single time range
  • SPDT Relay output
  • 17.5mm wide, DIN Rail mount

When power is applied, the output relay remains de-energised for the set time delay period. After the delay has elapsed, the relay energises. If the supply voltage drops below the fixed threshold for greater than the reset time, the relay will de-energise and timing will recommence as soon as the voltage increases above the threshold again.

  • Timing function: Delay On
  • Trip level: 80% of Un
  • Time delay: 2 – 60s
  • Reset time: 100ms
  • Output: SPDT 8A @ 250V (AC1)
  • Dimensions(mm): W:17.5 x H:89 x D:66.5

Supply voltage options*:
115VAC (Order Code: 99-2002)
230VAC (Order Code: 99-2003)

* To be specified when ordering.

Typical applications include:

  • Remote water pumping stations
  • Unmanned utility control panels
  • Industrial process equipment
  • Mains restoration control panels

Key benefits:

  • Helps inhibit operation during low voltage — The relay de-energises when the monitored supply falls below the fixed threshold for longer than the reset time.
  • Delays restarting after supply recovery — Once voltage recovers above the threshold and hysteresis, the relay waits for the selected period before energising.
  • Supports unattended recovery — The timing sequence recommences automatically after the supply returns to an acceptable level.
  • Lets the restart delay suit the equipment — The adjustable delay allows the recovery waiting period to be selected for the application.
