The TimeMark 22VB is a 3-phase monitor for 190-480 V AC, 50/60 Hz systems. It drops its output relay out on phase loss, phase reversal, over/under voltage and voltage unbalance and resets once the fault clears.
Trip points: undervoltage 185-480 V AC adjustable (resets 3% above the setting); overvoltage 208-528 V AC adjustable (resets 3% below the setting); unbalance 6% fixed (resets at 5%). Trip delay: undervoltage 1-30 s adjustable (over, under and unbalance); 1 s fixed on single phasing or unbalance over 15%. Restart: 1-500 s (adjustable). Reset: automatic.
Output: 2 x SPDT, 10 A at 240 V AC resistive. Mounting: DIN rail or surface mount. Indicator: Red and green status LEDs (UNDER, OVER, UNBAL/SINGLE PH, REVERSE PHASE on red; RUN, RESTART DELAY on green).
