Start up time is measured at nominal input and with a constant resistive load. 2. Cross regulation is measured with the output being tested at 50% load. The second output is varied from 10% to 100% load. 3. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 1 µF to 10 µF) be placed from the +VOUT to the -VOUT pins. 4. Short circuit protection is provided by a “hiccup mode” circuit. 5. Isolation capacitance for 24 VDC output models is 2,000 pF. Isolation capacitance is measured from input to output at 100 kHz/0.1V. 6. The maximum control current at the on/off pin (pin 6) during a logic high is 50 µA. The maximum control current to the on/off pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut off. 7. These units should not be operated with a load under 10% of full load. Operation at no-load will not damage the unit, but they may not meet all specifications. 8. These units should not be operated over +85°C. Exceeding +85°C may damage the unit. 9. It is recommended that a fuse be used on the input of a power supply for protection.

To adjust the output DOWN, connect a 5%, 3W resistor between the plus output pin and the Vout trim pin. To adjust the output UP, connect a 5%, 3W resistor between the minus output pin and the Vout trim pin. For UP/Down trimming capability, connect a 10 kW potentiometer between the plus and minus outputs with the wiper arm connected to the Vout trim pin. 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected] www.micropowerdirect.com EMC Specifications Parameter Radiated Emissions Conducted Emissions ESD RS EFT Surge CS Voltage Dips Standard See Note 1 EN 55022 See Note 1 EN 55022 EN 61000-4-2 EN 61000-4-3 See Note 2 EN 61000-4-4 See Note 3 EN 61000-4-5 EN 61000-4-6 EN 61000-4-29 Class A Class A Criteria B; ±4 kV Contact Criteria A; 10V/m Criteria B; ±2 kV Criteria B; ±2 kV Criteria A; 3 Vrms Criteria B; 0% - 70% Notes: 1.
