Low Noise, Proportional High Voltage Modules
0 to + or - 300 through 0 to + or - 3,000 VDC @ 1.5 Watts
L Series
The L Series is a line of small,
versatile, component level building
blocks that provide up to 3,000 VDC,
positive or negative, in a compact
PC mount package. The isolated
output is directly proportional to the
input. Either output may be grounded
to generate positive or negative high
voltage. Excellent filtering techniques

and a low noise sinewave oscillator
provide clean, reliable DC to HV DC
conversion with low ripple, noise, and
EMI/RFI. Two pin-out options are
available in this series; add an “A” or
“B” for your choice (see below). An
external metal enclosure is also
available, just add an “AB” to the
model number (i.e. L30BAB).

*Notes1. At Maximum Rated Output Voltage.
2. Output Voltage is load dependent. Under light or no load conditions, reduce input voltage so
maximum rated output voltage is not exceeded.
3. Pin-out pattern “A”or “B” must be specified with model number (e.g. L05B ),
see below.
4. Specifications after 30 minute warm-up, full load, at 25
o
C unless otherwise noted.
5. The rated output current is available at full output voltage and must be derated
pro
proportionally as the input voltage decreases. For example: a 500V, 1.5W unit, rated
at
at
at 3mA at 500V will provide 1.5mA at 250V out.
