PH-1100 single-phase voltage relay 100V is designed to monitor the presence and validity of voltage in the secondary circuits of measuring voltage transformers (VT). The device is engineered to switch electrical circuits within protection and automation systems of electrical installations exceeding 1000V. It reacts instantly to critical network voltage deviations, preventing automation malfunctions and substation equipment damage.
The PH-1100 is a reliable digital module housed in a compact DIN-rail case (2 S-modules), developed strictly for single-phase measuring grids with a nominal voltage of 100V (50 Hz). The unit measures and displays the root-mean-square (RMS) value of the input voltage on a three-digit LED display while indicating output relay status. Intuitive adjustment of trip thresholds (Umin from 50V to 95V, Umax from 105V to 150V) and shut-off time delays is achieved via convenient rotary knobs and toggle switches on the front panel.
Main Features & Operating Modes:
4 Independent Operating Modes: Functions as a minimum voltage relay, maximum voltage relay, dual-threshold voltage relay (Umin + Umax), or a turn-on time delay relay.
Instant Emergency Tripping: In the event of severe voltage drops (below 40V) or sharp surges (above 160V), the relay trips within a fixed ultra-fast timeframe (0.12–0.2 s), overriding user time delays.
Heavy-Duty Output Contacts: A changeover contact group rated up to 16 A (4000 VA) allows direct control of auxiliary relays and alarm circuits.
Automatic Reclosing (AR): Once input voltage returns to normal parameters, the device automatically re-energizes output contacts after a 1-second delay.
