Ordering Information：
- Measued from High line to Low line
- Measured from Full load to Zero load
- The Output ripple and noise is measured with 10uF tantalum and 1µF Ceramic capacitor across output.
- Logic compatibility ... Open Collector ref, to - Input
Module ON ... Open Circuit
Module OFF ... < 1.2VDC - Suffix "N" to the Model Number with Negative Logic Remote ON/OFF
Module ON.............. <1.2VDC
Module OFF............. Open Circuit - Trim-up....................Connect a Resistor Between the Trim Pin and +Sense Trim-Down...............Connect a Resistor Between the Trim Pin and -Sense
