The LHV-45 Series 45W electrostatic air and oil cleaner power supplies offer an auto-ranging ac input and 1 to 30 kVdc output voltages. Fully encapsulated, the power supplies provide constant-voltage, constant-power, and constant-current operation, which are requirements for electrostatic air filters and oil cleaners. Standard features include convection-cooled operation, over-current, short-circuit, and arc-protection circuits, ac-ok and dc-okay signals, and both voltage- and current-monitoring signals. Additionally, the supplies employ a patent-pending, recessed high-voltage poke-home output connector for safe operation and standard models measure 10.35” x 7.42” x 2.13”. Pricing starts at $198 each in OEM quantities. For further information, contact Matt Martis at LHV POWER INC., Santee, CA. (619) 258-7700.
