Quarter brick 150W converters target industrial and railway designs
Gresham Power Electronics has launched two series of 100W and 150W DC-DC converters from Polytron Devices for use in industrial and railway applications.

The QB100 and QB150 series feature a 4:1 ultra-wide input range and operating temperature of -40 to +110°C

The 100W QB100 series offers high efficiency up to 93% in a 58 x 36.8 x 12.7mm (2.28” x 1.45” x 0.50”) quarter brick package. The 150W QB150 series, available in the same size package, offers efficiency up to 92%.

Both converters feature remote control, no minimum load requirement and low standby power consumption; are CE marked and meet UL60950-1, EN60950-1 and IEC 60950-1 safety standard and are compliant with RoHS II and Reach guidelines.

Nominal input voltages are 24 Vdc (8.5 to 36 Vdc), 48 Vdc (16.5 to 75 Vdc) and 110 Vdc (40 to 160 Vdc) with single output voltages over the range 3.3 to 110Vdc

“Railway equipment and many industrial applications are required to operate in extreme weather conditions and from unregulated power sources" said Jake Moir, Managing Director of Gresham Power. "The QB100 and QB150DC:DC converters are designed to provide stable system power output in these demanding environments while being compact and cost effective.”

Gresham’s experience of designing and manufacturing defence power systems is available to customers to provide modified standard or full custom power supply designs if required. Gresham can also supply a new range of defence power products for land based or vehicle applications to complement its world-leading naval power systems.
