1.1 Description of the SLM Series
he SLM Series of high voltage generator modules are
designed for OEM applications up to 70kV and up to
1200watts. Its universal input, small package size and
choice of three standard digital interfaces simplifies
integrating the SLM into your system. DSP based control
circuitry provides excellent regulation, along with
outstanding stability performance. User programmable
firmware option makes the operation of the SLM flexible.
The dramatically reduced size of the SLM module,
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. The high efficiency is
obtained by zero current switching (ZCS) resonant
control. High operating frequency, typically 50 kHz,
allows for 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 SLM series operates from 90 -
265Vac, at 50/60 Hz single phase for the 300Watt models
and 180–264Vac, at 50/60 Hz single phase for the
600Watt and 1200Watt models. The input is power
factor corrected and the SLM series operates at full power
continuous. The ambient temperature must be kept below
the maximum rating as specified in 1.2. The standard
warranty applies to the modules. Consult factory about
the warranty for custom SLM modules.
