SSAC KSD3 Series Data Sheet
KSD3 SeriesTimer - Recycling Flasher
Connection:
RT is used when external adjustment is ordered.
L1 N/L2
The KSD3 Digi-Timer is a cost effective approach
for ON/OFF recycling applications. The on time
is equal to the off time. An adjustment of the RT
will change the time delays of both on and off
times. This series is designed for general purpose
commercial and industrial applications where a
small, cost effective, reliable, solid-state timer is
required. The factory calibration for xed time
delays is within 5% of the target time delay. The
repeat accuracy, under stable conditions, is 0.5% of
the selected time delay. This series is designed for
popular AC and DC voltages. Time delays of 0.1
seconds to 1000 minutes are available in 6 ranges.
The output is rated 1A steady and 10A inrush. The
modules are totally solid state and encapsulated
to protect the electronic circuitry.
Operation (Recycling Flasher - ON Time First):
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.
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to the ON time.
Operation (Recycling Flasher - OFF Time First):
Upon application of input voltage, the T2 OFF time
begins. At the end of the OFF time, the T1 ON time
begins and the load energizes. At the end of the ON time
the load de-energizes, and the cycle repeats until input
voltage is removed.
Reset: Removing input voltage resets the output and time
delays and the sequence to the OFF time.
