HOLES Note: Dimensions in inches. Multiply values by 25.4 for dimensions in mm. Notes: 1. Remove black screw for access to the voltage trip adjustment. 2. Clockwise rotation of the adjustment potentiometer will raise the voltage trip point. 11 Protective Relays Voltage sensitive relays are available for both AC and DC applications for over/undervoltage protection. Combination over/undervoltage relays provide bandpass capabilities. AC relays are either single or three-phase type. Three phase models are designed to sense the average of the three phases or the highest single phase. Voltage trip points are screwdriver adjustable, and operation is time-delayed so that momentary voltage transients will not cause nuisance tripping. Nominal Voltage — 120 VAC to 575 VAC Phase — Single or Three Line Frequency — 50-400 Hz Pick-up to Drop-out Differential — 2.5% maximum Drop-out Point (u/v models) — 70-100% of nominal voltage, screwdriver adjustable Pick-Up Point (o/v models) — 100-125% of nominal voltage, screwdriver adjustable Output Contacts — One set N.O., One set N.C. Contact Ratings — 5 amp resistive at 120 VAC or 28 VDC Operating Temperature Range — -20˚C to +65˚C Power Consumption — 2 VA maximum Time Delay — 150-300 ms (UV Model) Minimum Life — 500,000 operations Single Phase Three Phase Typical Time Curve Ordering Information 40.0 WUV -1 -120 Voltage Above Set Point Sample Part Number 䊳 Type: WUV - Undervoltage WOV - Overvoltage No. Phases 1 = Single 3 = Three Line Voltage VAC 120 416 208 440 220 460 230 480 240 525 380 575 30.0 Overvoltage Relays WOV Series 20.0 10.0 0.0 -10.0 0 Options P - Transient Protection A - Two Normally Open Contacts B - Two Normally Closed Contacts H - 125VDC, 3A Contacts 0.05 0.1 0.15 0.2 Pick-Up Time Delay 0.25 0.3 Transient Protection — All voltage relays will withstand momentary voltage surges of twice the nominal rated input voltage (standard).
