Ripple Vo ( 120 Hz) 1.00 V p:p Vo is a voltage-regulated output which has a constant ( 100 kHz) 0.25 V p:p power mode instead of a conventional current limit. This For Vo = 8V, Ir out 160mA max, Io+Ir 250mA* Output Vr, 3.3 volt (+/- 5%) output is best suited to drive mechanical relays, solenoids, For Vo = 14V, Ir out 70mA max, Io+Ir 143mA* SSRs, capacitive loads, indicating lights, LEDs and as a For Vo = 8V, Ir out 250mA max, Io+Ir 250mA* Output Vr, 5.0 volt (+/- 5%) source for isolated DC utility power which may be used For Vo = 14V, Ir out 83mA max, Io+Ir 143mA* directly or post-regulated with either a linear regulator or a No-load Consumption 30 mW typical Vin=120 VAC DC/DC converter. Vo is self protecting, cannot be over- loaded and can be shorted indefinitely. The graceful transi- Isolation 3000 VAC (meets UL / CSA & EN Product Safety) tion from voltage regulation to constant power along with the wide range of product ratings, allows the designer to Earth Leakage 120 VAC < 10 uA select a supply tightly matched to the design load. There is Short Circuit Protection Continuous, Pin 0.6 w Vin = 120 VAC no need to oversize a Bias Power supply. Unlike design- your-own, or partially complete modules where significant Reliability 25 C, MIL HDBK-217F > 500 Khr MTBF design margin is required, to stay far away from current Thermal limit, Biass constant power alternative requires no such over-specing. Operating Temperature -30 to +70 C Operating Relative Humidity 0 95%, non-condensing Vr is also a voltage-regulated output and is thermally pro- tected from overload.

In addition, Vr is supplied internally by Vo. This (L x W x H) 34.214 x 28.372 x 14.757 mm means that any capacitance added to Vo can increase the Safety hold-up time of Vr as well. *Note: maximum currents specified for constant voltage Safety Compliance UL / EN 60950-1 2nd Ed.
