14kV/06mA High Voltage Power Supply for Electrostatic Air Cleaner
1. Overview
The 14kVDC/06mA HV power supply is an OEM product and comes without AC
power ON/OFF controls and safety interlocks. It is system integrator
responsibility to assure that all national, state and local electrical safety codes
are followed.
1.1 Principle of operation
The block diagram of HV Power Supply is shown in Fig. 1
The HV Power supply has built in universal input, power factor corrected AC/DC power
converter, which produces 450VDC for the resonant DC/DC HV power converter. The
Resonant Power Converter drives the HV step up transformer, which delivers up to
1.5kV RMS to the HV multiplier. The 4 stage HV multiplier produces up to 14kVDC at
the output (Ionizer) and 7kVDC at the output of second stage (collector).
This PS has capabilities to deliver up to 6mA DC current at 14KVDC to 2 X 24" Linear
cells.
The resonant power converter is over voltage, over current, overpower protected
including continuous output short circuit condition.
Operating HV and output current limit are set manually however Intelligent Controller
has the capability to perform the following functions:
1. Monitors internal ambient temperature and turns HV converter off if temperature
is outside operating limits.
2. Monitors HV and output current
3. Maintain the best performance and minimize load cell arcing
4. Reports HV converter status using LED Lamps and optional serial messages on
RS-485 port or Modbus.
Operating HV, Current, Temperature, number of hours of operation, error codes
can be monitored on optional RS-485 output or Modus output terminals.
