Output Trim Equations Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected between the Trim pin and Sense (-) pin. The Trim Up resistor should be connected between the Trim pin and the Sense (+). Only one of the resistors should be used for any given application. Minimum trim down voltage is 10.8V Maximum trim up voltage is 13.2V. The total voltage increased by trim and remote sense should not exceed 10% of the nominal output voltage. 511 Rtrimdown = − 10.22[kΩ ] delta Sense(+) Module Trim Rtrimdown Sense(-) Rtrimup= (100+ delta ⋅ Vo⋅ 5.11− 626 ) −10.22[kΩ] 1.225⋅ delta Sense(+) Rtrimup Module Trim Sense(-) Note: delta = (Vo _ req − Vo) ×100[%] Vo Vo_req=Desired (trimmed) output voltage [V] Output voltage Vo=12.036V 600 R trim _ d ow n (K o hm ) 2 500 R trim _u p (K ohm ) 2 000 1 500 1 000 500 0 1 1. 0 4 11 .2 8 1 1 .5 2 V o ,ad j (V) 1 1. 7 6 12 480 360 240 120 0 1 0 .8 12 1 2 .24 12.48 12.7 2 Vo,adj (V) 12 .96 13 .2 Bel Fuse Inc. 206 Van Vorst Street, Jersey City, NJ 07302 • Tel 201-432-0463 • Fax 201-432-9542 • www.belfuse.com 9 ISOLATED DC/DC CONVERTERS 24 Vdc Input Sep. 11, 2010 12 Vdc /20 A Output Bel Power Inc., a subsidiary of Bel Fuse Inc. Remote Sense This module has remote sense compensation feature. It can minimize the effects of resistance between module’s output and load in system layout and facilitates accurate voltage regulation at load terminals or other selected point. 1. The remote sense lines carries very little current and hence do not require a large cross-sectional area. 2. This module compensates for a maximum drop of 10% of the nominal output voltage. 3. If the unit is already trimmed up, the available remote sense compensation range should be correspondingly reduced. The total voltage increased by trim and remote sense should not exceed 10% of the nominal output voltage. 4. When using remote sense compensation, all the resistance, parasitic inductance and capacitance of the system are incorporated within the feedback loop of this module. The can make an effect on the module's compensation, affecting the stability and dynamic response. A 0.1uF ceramic capacitor can be connected at the point of load to de-couple noise on the sense wires. 5. Recommend the connection of remote sense compensation as below figure. There are a resistor RS+ (100 ohm) from Vo+ to Sense+ and a resistor RS- (51 ohm)) from Vo- to Sense- inside of this module. Vo+ RS+ Sense+ Load SenseRS- V o- 6. If not using remote sense compensation, please connect sense directly to output at module's pin, that is, connect sense+ to Vo+ and sense- to Vo- at module's pin, the shorter the better.

Over Current Protection To provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry and can endure current limiting for a few mili-seconds. If the over current condition persists beyond a few milliseconds, the module will shut down into hiccup mode and restart once every 800mS. The module operates normally when the output current goes into specified range. The typical average output current is 0.02A during hiccup. Vin = 24 V, Load in CC Mode CH1: Output Voltage CH3: Output Current Expansion of on time portion Over Voltage Protection The output overvoltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over voltage protection threshold the module will shutdown into latch off mode. The overvoltage latch can be reset by either cycling the input power or toggling the on/off signal for one second at least.
