SDAS-O1 series
1.5 TO 15 AMP AC CURRENT SENSOR
· Zero insertion loss
· Inductive coupling to power line
· Choice of modes
- Adjustable overcurrent sensor
- Adjustable undercurrent sensor
· Solid state sensing circuit
· 1 Form C (SPDT) or 2 Form C (DPDT) internal relay
SENSING MODES:
Overcurrent sensor - Detects a current in excess of
the value determined by the potentiometer setting. A built-in
time delay, 200 ms, minimum, allows for normal starting and surge
currents. Actual time delay is dependent upon potentiometer setting
and magnitude of overcurrent. Any overcurrent lasting longer than
this causes the internal relay of the SDAS01 to energize. The
relay will remain energized until sensor control voltage is removed,
even if the overcurrent ceases to exist.
Undercurrent sensor - Reacts to a complete loss of
sense current, or any current of less than the potentiometer setting.
Upon application of sensor control voltage, there is a nominal
350ms delay during which time power line current must begin. This
delay gives line components time to turn on. If, at the end of
the delay, sense current should decrease to less than the potentiometer
setting of the SDAS-O1 and remain there for approximately 350
ms, the internal relay of the SDAS-O1 will energize. It will remain
energized until either sense control current again exceeds the
potentiometer setting, or until sensor control voltage is removed.
ENGINEERING DATA:
Control Voltage: 24VAC 50/60 Hz./DC +/- 10%.
Sense-Current Range: 1.5 to 15 amps AC.
Internal Relay Contact Data:
1 Form C (SPDT) type (code X1): 5A @ 28VDC or 2.5A @ 120VAC, res.
2 Form C (DPDT) type (code Y2): 2A @ 28VDC or 1A @ 120VAC, res.
Set Point Variation: +/- 25% over operating temperature range.
Time Delay:
Overcurrent sensor: 200 ms, min., after beginning of
overcurrent. Actual delay is dependent upon potentiometer setting
and magnitude of overcurrent (see Figure 1).

of undercurrent after control voltage is applied.
