POWER SUPPLY - ZXM-2A
3.682”
Ø .172”
2.90”
The power supply is a current type. Output current is
maintained constant, even while the load resistance
changes, which is typical of any brake or clutch coil
when temperature changes.
Output: 0 - 2 Amperes DC. Output current is controlled

ADJUSTMENTS - When Using Manual (Potentiometer) Control:
CURRENT ADJUST POTENTIOMETER - The remotely mountable potentiometer controls the desired output current,
and is adjustable from 0% to 100%. This is used to control output torque. For applications with maximum
current less than 1 Ampere, use a 10 turn potentiometer with scale dial for easy, fine control.
OPTIONAL SPAN MIN POTENTIOMETER
Without a SPAN MIN potentiometer, the CURRENT ADJUST potentiometer must be increased a small amount,
EHIRUHFXUUHQWLQFUHDVHVDERYH7RHOLPLQDWHWKLVGHDG]RQHDGGDŸ63$10,1SRWHQWLRPHWHUDVVKRZQ
To adjust: Set the CURRENT ADJUST pot to 0. Increase the SPAN MIN pot setting until the output current starts
increasing. A SPAN MIN potentiometer is recommended for applications under 750 mAmps, for ease of control.
OPTIONAL SPAN MAX POTENTIOMETER OR RESISTOR
The SPAN MAX resistor (or potentiometer) sets the maximum output current. For example, with an approximately
