Product Summary

The HiWatt 2 UV arc lamp ballast is a dual processor controlled solid-state switching power supply, that consists of two power stages; a square wave AC output converter & igniter for powering a mercury vapor or halide arc lamp, and an auxiliary DC power supply for providing 24VDC (6Amps) for user controls and cooling fans. The HiWatt is designed to be factory or customer software configurable (via PC serial port) to allow the unit to adapt to a wide range of lamp types, and utility power sources. This capability will allow the unit to power an arc amp in the range of 1kW to 20kW, with lamp voltages of 200 to 850V, from single or 3 phase AC sources of 208/240/480V 60Hz – 200/230/380/415V 50Hz. The unit may be used to power two arc lamps in series as long as the total composite voltage does not exceed 850V. This programmability makes the HiWatt a truly universal arc lamp ballast that will allow it to be utilized as a single unit solution for powering many types of lamps from power sources worldwide.

PC/PLC Control Interface

The HiWatt has the ability to communicate to customer connected controllers or PCs via optically isolated digital logic signals, RS485 serial port or USB port. The logic signals include status lines for lamp ignited, lamp ready (warm-up-complete), and unit alarm, as well as control signals for lamp enable/disable, and lamp dimming (via PWM control, pulse frequency or 0 to 10V). Lamp cooling blower control is also provided, with blower On/Off signal, air temperature/flow regulation and lamp temperature monitoring. The unit can optionally control motorized or pneumatic lamp shutters. Units can also be networked to provide customer interface to multiple HiWatt slave units from the RS485 ports. This option will allow interface to multiple lamp systems cascaded on a single high-speed product line, which can still be controlled and monitored as a single system with much higher power capability.
