PTHF Series
Power Timing Module

Description

The PTHF Series can be used for a variety of applications from chemical metering, to temperature regulating, to
energy management. The infinite adjustability from 1 to 99% provides accurate percentage ON control over a wide
factory fixed cycle period. When mounted on a metal surface, it can be used to drive solenoids, contactors, relays,
or lamps, up to 20 Amps steady, 200 Amps inrush. PTHF is the suggested replacement for the PT Series.

Operation

Upon application of input voltage, the output energizes
and the T1 ON time begins. At the end of the ON time,
the output de-energizes and the T2 OFF time begins.
At the end of the OFF time, the output energizes and
the cycle repeats as long as input voltage is applied.
Increasing the ON time decreases the OFF time. The
total cycle period is equal to the ON time plus the OFF
time. The total cycle period is factory fixed. ON time
range is 1 to 99 percent of cycle period.
Reset: Removing input voltage resets the output
and time delays, and returns the sequence to the T1
ON time.
