**Note:** Dimensions in inches. Multiply values by 25.4 for dimensions in mm. 

## **Product Specifications** 

**Nominal Voltage (±10%)** — 12 VDC to 560 VDC **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** — -40˚C to +75˚C 

**Temperature Effects** — Less than 1% voltage drift over the temperature range. 

**Power Consumption** — 12 to 60 VDC models — 1 W max. 120 to 305 VDC models — 2 W max. 405 to 470 VDC models — 3 W max. 560 VDC Model — 4 W max. 

**Time Delay** — A short duration delay is provided to prevent nuisance tripping due to momentary dips or surges in voltage.  The drop-out delay, following a voltage fault is 75 to 100 milliseconds 

## **Notes:** 

1. Remove black screws for access to the O/V and U/V trip adjustment.

2.  Clockwise rotation of the adjustment potentiometer will raise the voltage trip point. 

3. The adjustments are by means of a single turn potentiometer. Use a small screwdriver and do not force beyond the limit stops.

**Transient Protection** — All voltage relays will withstand momentary voltage surges of twice the nominal rated input voltage (standard). 

**Option “P”** provides additional transient protection which complies with the requirements of ANSI/IEEE C37.90-1978 **Consult factory for additional models.**
