Adjusts from 6 seconds to 8 minutes. Spin-proof knob. Works with 24, 120 or 240 VAC control circuits. Supports up to 1.5 Amps. Two wire hookup for easy installation. Solid state with quick disconnect terminals. Mounts with one self-tapping screw. Conformal coated circuitry protects against moisture and shock. UR recognized for USA and Canada. Work with anticipator type thermostats.

HOW IT WORKS

Immediately upon application of power, the Delay on Break timer enables circuit operation. Once power is interrupted, the circuit opens for the time set on the dial. After the time period elapses, the circuit closes, allowing the protected motor or compressor to start. For typical HVAC applications, the operation of the timer is transparent and will go unnoticed.

HOW IT WORKS

These timers delay circuit closure upon application of power. Only after the set time period elapses and power remains ON will the circuit close, allowing the protected motor or compressor to start. For typical HVAC installations, timers are adjusted to random times to prevent power circuit overloads. They are sometimes called random start timers.

An automatic voltage monitor and control system. By continuously measuring the incoming line voltage, this monitor will detect any voltage outside the tolerances that you set. If these limits are exceeded, the response timer will begin counting. You may also set the response time – a short time may be desired for a quick response or a long time to avoid nuisance tripping. If the voltage remains outside the tolerance after the time has elapsed, the DSP-1 will turn off its output relay and protect your device. While the output is off, an additional delay timer is activiated to avoid rapid restarts.

FEATURES

Digital voltmeter displays instantaneous line voltage. Automatic voltage tester adjusts from 90-300 volts. Adjustable response timer (0.1 to 10 sec.) prevents nuisance tripping. Adjustable delay timer (1 to 720 sec.) prevents rapid restarts. Digital display makes for easy viewing and operation.
