Remote On/Off
Notes:
1. Start up time is measured at nominal input and with a constant resistive load. Applying a signal to pin 3 will turn the unit ON/OFF. If the pin is left open, the unit operates. If
2. Load regulation is specifi ed for a load change of minimum load to full load. grounded, the unit will shut off. The specifi cations for the ON/OFF function are:
3. Cross regulation is measured with the output being tested at 100% load. The second output is varied from 25% to 100% load.
4. When measuring output ripple, it is recommended that an external 1 µF capacitor and 10 µF capacitor be connected in Parameter Min Typ Max Units
parallel from the +VOUT to the -VOUT pins for single output units and from each output to common for dual output units. Supply On 3.5 12.0 VDC
5. Transient recovery is measured to within a 1% error band for a load step change of 25%. Supply Off 0.0 1.2 VDC
6. Short circuit protection is provided by a “hiccup mode” circuit. Standby Input Current 2.5 mA
7. The switching frequency for 24 VDC output models is 285 kHz. Control Common Referenced to Negative Input (pin 2)
8. Operation at no-load will not damage these units. However, they may not meet all specifi cations if operated below the Control Input Current (ON)
specifi ed minimum load. 0.5 mA
9. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table Control Input Current (OFF) -0.5 mA
above for the correct rating.
