Marsh Bellofram Diversified Electronics Division ASC-500 Series HVAC Delay-on-Break Timer

Product catalog summary

Overview: The ASC-500 Series by Diversified Electronics provides short cycle protection for compressors by locking them out for a set period after a voltage or thermostat interruption. This prevents the delay period from increasing with subsequent interruptions and ensures that temperature control remains unaffected. The typical compressor off time exceeds five minutes, so these timers do not extend the off cycle under normal conditions.

Features: These are two-terminal Short Cycle Timers that are easy to install and connect in series with the control voltage and relay. The 24 VAC model includes a built-in bypass circuit for continuous flow through the thermostat's cooling anticipator when the timer output is off.

Ordering Information: The series includes three models: ASC-500-5, ASC-501-5, and ASC-502-5, all of which are Delay-On-Break Timers.

Specifications:

Control Voltage: ASC-500-5 operates at 24 VAC, ASC-501-5 at 110/120 VAC, and ASC-502-5 at 208/240 VAC.
Output Rating: ASC-500-5 has an inrush of 250 VA and a run of 25 VA at 24 VAC. ASC-501-5 and ASC-502-5 both have an inrush of 1250 VA and a run of 125 VA at their respective voltages.
Time Delay: 5 minutes with a tolerance of ±20%.
Dimensions: 2.0" x 2.0" x 0.75" high.
Weight: 3 oz.

ASC-500 Series Diversified Electronics atcdiversified.com 800.727.5646 268HVAC Controls // ASC-500 Series This family of controls provides short cycle protection by locking out the compressor for a period of time after a voltage or thermostat interruption. Subsequent interruptions will not increase the delay period. Since the delay begins when the interruption occurs, the temperature control is not affected. Under normal operating conditions, the compressor off time is longer than five (5) minutes. In this case, the use of these timers will not lengthen this off cycle. These are easy to install two (2) terminal Short Cycle Timers that connect in series with the control voltage and control relay. The 24 VAC model employs a built-in bypass circuit for allowing continuous flow through the thermostat’s cooling anticipator while the timer output is off.
