Note
1.
Maximum output deviation is 10% inclusive of remote sense. If remote sense is not being used, the +V sense should be connected to its corresponding
+OUTPUT and likewise the –sense should be connected to its corresponding –OUTPUT.
2.
Measured with a 1uF M/C and a 10uF T/C.
3.
An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V/24V models. Power
mate suggest: Nippon chemi-con KMF series, 220 F/100V, ESR 90m .
4.
The negative/ positive logic and pin length are optional ( see table ). The pin voltage is referenced to negative input.
5.
24V input models safety approval pending.
6.
Heat sink is optional and P/N: 7G-0021, 7G-0022, 7G-0023, 7G-0024.
7.
The HEC50 meets level A and level B conducted emissions only with external components connected before the input pin to the converter.
8.
Maximum value at nominal input voltage and full load.
9.
Typical value at nominal input voltage and full load.
10.
BASEPLATE GROUNDING
Base-plate should be grounded at one of the four screw bolts prior to operation.
11.
The converter is provided by basic insulation.
