Powertec Supplies India Pvt. Ltd. offers Dc/DcEncapsulated Modules. These DC/DC Encapsulated Modules uses the SMD technology for assembly [PCB mounting] renders a height of 7 mm to 12.7 mm for power handling from 1.5 W to 100 W for a switch mode regulated and fixed output power source. AC/DC converter modules are also available up to 15 W with inputs of 85-264 V AC. The AC/DC and DC/DC converters are PCB mountable with built-in protection for overvoltage, overload and thermal trip. They carry safety approvals like UL, CSA, TUV, IEC, and EN60950, apart from radiation clearances FCC-B and VCCI2. Each unit undergoes severe environmental, climatic, shock and vibration tests prior to availability for users. General operating temperatures range from -20?C to 75?C. Encapsulation of modules enhances capability to withstand 50G shock as well as 20G for vibration, high humidity with dusty, corrosive and tropical environments. Input voltages range from 4.5 V to 72 V DC [user selectable] or 88-370 V DC with output voltages 5 V, ? 12 V, ? 15 V and power handling up to 100 W per module. These can be paralleled or used in master/slave configuration for higher delivery. Available from Cosel, Japan, through a collaboration agreement with a power supply manufacturer of repute, these are presently marketed by Powertec Supplies India Pvt Ltd, NOIDA, shortly to start indigenous manufacture.
