Product- SDC Specification Date : 10.01.2005 Type : SDC 60/15-20 Product Range : Step-Down DC/DC Converter 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 for mounting Features: - Adjustable output voltage - Short circuit protection - Connecting in parallel - Stand-by function - Remote ON/OFF - High efficiency Specification Input Input voltage range: : 10...60Vdc No load input current : 40mA Remote ON/OFF : Inhibit >3V , Operate <1V Output Output voltage : 4.5 to 15Vdc Output current : 0...20A Tolerance: : < 3% Line regulation: : <2% Ripple and noise : 150mVpp Temperature coefficient : 3mV/C Input/Output Differential : 3.5V( Uin > 15V), 5V(Uin < 15V) Remote sense : Remove JP1 for remote sense operation Output current limit (factory set) : 24...27A ( however , when units are used in parallel configuration, the current limit should be set at 20A with R25 on PCB) General Efficiency : 75% typical Switching frequency : 25KHz Weight : 0,4 kg Dimension W x H x D : 127 x 45 x 136 mm Environment Thermal performance : 0C to +70C Max. Heat sink temperature : +80C Relative humidity : Non - condensing 5% to 80% Safety : acc. to EN 60950 subject to change without notice Product- SDC Specification Date : 10.01.2005 Mechanical notes remove JP2 to synchronise to other regulators remove JP1 for remote sense Important Hints With the help of spacers the module should be fixed at the heat sink. The efficiency of the heat sink must be sufficient. The contacts (INPUT+, OUTPUT+ and GND) will be guaranteed by stud bolts (diameter: 4mm).
