Typical Applications
Pico Series SA and SA-SM converters are suitable for compact high voltage circuits that require isolated DC-DC conversion in a small footprint. Typical applications include:
High voltage bias supply
Photomultiplier tube bias circuits
Avalanche photodiode bias circuits
Electrostatic and sensor systems
Industrial test and measurement equipment
Portable and embedded high voltage modules
Laboratory and instrumentation power supplies
Why Choose Pico Series SA & SA-SM?
The Series SA and SA-SM provide a compact way to generate high voltage output from common low voltage DC inputs. With no minimum load, isolated output, low ripple and both through-hole and surface-mount package options, the series gives engineers flexibility when designing space-constrained high voltage circuits.
For model selection, choose the required nominal input voltage first, then select the required output voltage from 100V to 1000V. Use the SA version for through-hole PCB mounting and the SA-SM version for surface-mount PCB assembly.
