Proportional microsize HV power supplies offer improved output voltage stability
UltraVolt’s PXS Series of proportional extra-small devices claims to offer excellent load regulation of 5% as well as improved output ripple for a device of this type. The units’ small size 0.5 x 0.5 x 0.4 inch [12.7 x 12.7 x 10.2 mm], ease of control, reduced input current and increased efficiency compared to other devices make the PXS Series optimal for applications such as hand-held devices, portable equipment, and other small high-voltage projects. More specifically, applications designed and optimized for the PXS Series include pin diodes, avalanche photo diodes (APDs), piezoelectric devices, and more.
The volume for the ultra-miniature PXS Series is 0.1 in3 [1.64 cc]. Output voltages for the new line range from 50V through 300V for Unipolar models and ±25 V through ±150 V for Bipolar models, at 0 to 1.5 W of output power, with proportional or fixed output voltage. Excellent load regulation gives the PXS Series high efficiency – up to 90% – with 1000 V of isolation from input to output. Either output can be floated up to 1 kV or grounded to set polarity; no heat sink or electrical derating is required.
