INTRODUCTION
1.1 Description of The CZE Series
he CZE series of high voltage power supplies
provides very well regulated, low ripple high voltage
in a highly efficient, compact design. The
dramatically reduced size of these modules, compared to
traditional high voltage modules, is obtained by a state-of-
the-art off-line resonant converter. The resonant converter
utilizes a unique control scheme, which allows constant
frequency operation while maintaining high efficiency.
High operating frequency allows for very low ripple and
excellent dynamic response capabilities.
The DC output voltage and current are controllable over
the full range of operation. Monitoring and control
signals are provided for simple, yet flexible control of the
power supply. The CZE series operates from 24VDC
±10%. (User should specify the input voltage at the time
of ordering). The CZE series operates at 9W continuous.
The series does not require forced air cooling. The
ambient temperature must be kept below the maximum
rating as specified in 1.2. Consult Spellman Sales
Department for higher power capabilities of the CZE
series.
The standard warranty applies to the CZE series modules.
Consult factory about the warranty for custom modules.
1.2 CZE Specifications
•Output Control: Voltage and current are externally
programmable over the entire range from zero to

potentiometer. (Other scale factors for control and
monitoring can be provided i.e. 1 volt per 10KV, 1
volt per 1mA etc.).
