2. DESCRIPTION
Each Chargemaster VCM Electrostatic Generating Power Supply incorporates high
frequency switch-mode and power factor corrected technology within a compact
enclosure. Each unit is electronically current limited and arc protected. The output
voltage is adjustable from zero to full rated output at maximum rated current. Refer
to specifications for specific models.
The VCM30 and VCM60 power supplies are manufactured in either positive or
negative polarity, and feature remote ON/OFF capability. The output voltage can
also be controlled from a remote location via a 0-5V, 0-10V, 0-20 mA or 4-20 mA
voltage or current source. The power supplies also supply a 0-5V, 0-10V, 0-20 mA
or 4-20 mA output signal to remotely monitor the output voltage and current.
