SDC60/30-12 Block

Product Specification Product th Date : September 30 , 2009 SDC 60/30-12 Type : SDC 60/30-12 Step-Down Converter DC/DC Description : Versatile switching regulator with a single adjustable stabilized output from a DC source. The efficiency is essentially independent of input voltage. Output current need not be derated with increasing input voltage. The open version guarantees many possibilities of mounting. Features : - Adjustable output voltage - Short circuit protection - Connecting in parallel - Stand-by function - Remote ON/OFF - High efficiency - Shake proof Safety : acc. to EN 60950 Specifications : Input Input voltage range : 1060Vdc No load input current : 40mA Remote ON/OFF : Inhibit >3V / Operate <1V Output Output voltage : 4.530Vdc (set with potentiometer R7) Fig. 1 Output current : 012A (shows SDC 60/30-12 Tolerance : <3% without the hot melt glue) Line regulation : <2% Ripple and noise : 150mVpp Temperature coefficient : 3mVdc/C Input/Output Differential : 3.5Vdc (Uin >15Vdc) / 5Vdc (Uin <15Vdc) Remote sense : remove JP2 for remote sense operation Output current limit : 17A 10% General Efficiency : typical 75% Switching frequency : 25kHz Weight : 0.4kg Dimension W x H x D : 127mm x 51mm x 137mm Environment Thermal performance : 0C+50C (max. heat sink temperature: +80C) Relative humidity : 5%80% no dewfall Mechanical notes Remove JP1 to synchronise by master converter Remove JP2 for Sense (and +Sense) No changes on PCB for +Sense (only) Important Hints The module should be fixed at the heat sink and the opposite edges of the PCB an elastic mounting is highly recommended. The efficiency of the heat sink must be sufficient. The contacts (INPUT+, OUTPUT+ and GND/RET) are realized by metric stud bolts (diameter: 4mm). The feedthroughs are intended for the signal contacts.
