Voltage Monitoring Relays

202-200-SP Series

Single-phase voltage monitor

Description

The 202-200-SP series voltage monitor is designed to protect single-phase motors regardless of their size. It can be

used with 190–240 V ac, 50*/60 Hz motors to prevent damage caused by incoming power problems. A unique

microcontroller-based, voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions.

The MotorSaver^®deactivates its output relay after a specified trip delay whenever harmful conditions are detected. The

output relay reactivates after power line conditions return to an acceptable level and a specified amount of time has

elapsed (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.

*Note: 50 Hz will increase all delay timers by 20%.

Features & Beneﬁts

FEATURES

BENEFITS

Constant monitoring of voltage to detect harmful power line

conditions, even before a motor starts

Proprietary microcontroller-based circuitry

Prevents nuisance tripping due to rapidly fluctuating power

line conditions

Fixed trip delay 4 s

Allows staggered start-up of multiple motors after a fault to prevent

a low-voltage condition

Adjustable restart delay (manual, 2–3 s)

Advanced LED indication

Provides diagnostics that can be used for troubleshooting and to

determine relay status

One screw mounting and standard

¼” quick-connect terminals

Fast installation and compact size are perfect for panel assembly

or OEM applications

Applications
