D263SGM
The Model 263 continuously monitors 3-phase power systems for phase loss, low voltage and phase reversal. The monitor consists of a solid-state sensing circuit, driving an electromechanical relay.Applying correct voltage and phase rotation energizes the relay. When properly adjusted, a fault condition will cause the relay to de-energize, even when regenerated voltage is present.
When the fault is corrected, the Model 263 automatically resets. A manual reset version and an option for gold-plated contacts are also available.
The Model 263 does not require a neutral connection, and can be used on Wye or Delta systems. Each of the five different voltage ranges is adjustable to allow the monitor to be set for existing conditions. NORMAL and TRIP LED indicators are provided to aid in adjustment and system troubleshooting.

D2644
The Model 2644 3-Phase Monitor continuously monitors 3-phase Wye or Delta systems for abnormal conditions.The solid-state electronic sensing circuitry drives an internal DPDT relay, allowing the Model 2644 to operate two motor control circuits, or a control circuit and an alarm circuit. An adjustable trip delay reduces or eliminates nuisance tripping caused by momentary voltage fluctuations on motor start-up. An optional restart delay gives approximately a 3.5-minute delay when the relay drops out, to allow compressor head pressures to bleed off, in the event of short-term power failures.
Voltage adjustment ranges are sufficiently wide to allow for proper calibration to existing conditions. Both TRIP and NORM indicators are provided to aid in adjustment and system troubleshooting. Automatic and manual reset versions are available. The Model 2644 Monitor is not sensitive to line current, and can be used with any size motor or compressor.

D265
The Model 265 3-Phase Monitor continuously monitors 3-phase Wye or Delta systems for phase loss, low voltage and phase reversal. When properly adjusted, the Model 265 Monitor will detect phase loss on a loaded motor even when regenerated voltage is present.The solid-state sensing circuit drives an internal relay, in a fail-safe configuration, i. e. , the relay is energized when correct voltage and phase rotation are applied.
Operating power for the Model 265 is drawn from the 3-phase lines being monitored. An adjustable timer delays restarting of the load, allowing up to five minutes for compressor head pressures to bleed off, in the event of short-term power failures.
The Model 265 Monitor is not sensitive to line current, and can be used with any size motor or compressor. Automatic and manual reset versions are available.

D2652
The Model 2652 3-Phase Monitor is designed to protect motors, pumps, HVAC equipment, air compressors, etc. , by sensing phase loss, low voltage or phase reversal.With correct power applied, the DPDT output contacts transfer, and drop out when a fault condition or loss of power occurs. An adjustable trip delay prevents nuisance tripping. The restart delay timer prevents short cycling, which is primarily used with HVAC and compressor motors.
The DPDT output contacts allow the Model 2652 to be used in control circuits and alarm circuits. The automatic reset version can be converted to a manual reset, by adding a normally closed switch. The different voltage versions of the Model 2652 can be adjusted over a wide operating range. This unit is housed in an ABS plastic surface-mount case to reduce space requirements.

DC260B-160-250
The Model 260 Voltage Sensor is a single set-point voltage sensor. Input voltages above the set-point cause the output contacts to energize (contacts 1 & 8 closed). Input voltages below the set-point cause the output contacts to de-energize (contacts 1 & 2 closed). The dead band between pull-in and drop-out is less than 2%.The standard unit has a screwdriver, or fingertip adjustable set-point range of approximately 35%. of the maximum voltage. This device can also be provided with a factory calibrated trip point.
AC versions of the Model 260 Voltage Sensor are not frequency sensitive, and may be used in systems from 50 Hz to 400 Hz. DC models are not polarity sensitive. This device requires a standard 8-pin socket, such as Time Mark’s Model 51×120.
