PEAK electronics has expanded its proven DC/DC converter family in DIP24 package with the PMRW series (P34TG), which features a 5:1 ultra-wide input. The new modules are available with two input ranges from 13 VDC to 70 VDC and from 42 VDC to 176 VDC, and were specially designed for use in railway applications. The DC/DC converters of the PMRW series deliver regulated output voltages of 3.3, 5, 12 and 15 VDC, and are available both as single and dual output.
The power is 8 watt and the high efficiency ranges up to 86 %, depending on the module. The input/output isolation is 3000 VDC (3 kV DC). A continuous short circuit protection with automatic recovery is included. Furthermore, the devices provide overvoltage and overcurrent protection. All DC/DC modules come in a 1.25 inch (31.8 mm) x 0.8 inch (20.3 mm) compact DIP24 metal case including remote on/off control pin. The operating temperature range is from -40°C to +85°C.
