Pulsar DCDC15H Manuals

1 DCDC15H 12V/1,5A/62MM DC/DC converter Edition: 5 from 10.06.2014 Supersedes edition: 4 from 01.04.2014 EN Features:  Power output 1,5A/12VDC*  DC power supply range 18÷40V DC  high efficiency 86%  IP 67 enclosure  protections:  against short circuit protection  overload protection OLP  against reverse input voltage polarity  warranty – 2 year from the production date 1. Technical description. 1.1. General description. The DCDC converter is used for powering devices that require stabilized voltage of 12V DC. The maximum current load is 1.5A* (Pmax= 18W). This module does not have galvanic insulation between the input and output (IN-AUX), and operates on a common ground potential. The unit is protected against short circuit, overload and against reverse input voltage polarity. 1.2. Specifications. Supply voltage 18 ÷40V DC Supply power 18W max. Efficiency 86% Current consumption by PSU systems 5mA max. Output voltage 12V DC Output current tAMB<30°C 1,5 A - refer to graph 1. Output current tAMB=40°C 1,0 A - refer to graph 1. Ripple voltage 100mV p-p max. Protection against short circuits (SCP) and overloads (OLP) 200% ÷ 250% of module power – output power limit, automatic return after elimination of short circuit IP protection class IP67 Operation conditions temperature -10 oC÷40 oC relative humidity 20%...90% Dimensions (LxWxH) 58 x 58 x 28 [mm] Net/gross weight 0,16kg / 0,19kg Protection class PN-EN 60950-1:2007 II (second) Length of DC input cable 0,3m Length of DC output cable 0,5m + plug DC5,5/2,1 female Storage temperature -20ºC...+60ºC * In order to extend the life of the converter, the load current of 1,0A is recommended.
