The LPS-200-H 200-watt Lamp Power Supplies provide a precision regulated DC constant current source for the optimum operation of halogen filament lamps. They provide highly accurate currents (±0.1% ±2.0 mA of set value) for lamp standard measurements. The LPS-200-H lamp power supplies are operated from 110-120/220-240 VAC; 50/60 Hz and will maintain their output accuracy over a range of ±10% in line voltage fluctuations.
The front panel functions include four control buttons (power, start, stop, option) used for powering up the instrument and starting and stopping the current flow to the lamp. The operator uses the front panel to set the desired current or Labsphere light source. The power supply slowly ramps up to the desired setting (ramp-up time is approximately 2 minutes). This ramp-up circuit prevents the high transient currents associated with filament lamps, which shorten their lifetime.
Compatible Lamps and Light Sources: 4.4, 6, 10, 20, 30, 35, 75, 80, 120, 125, and 150 Watt.
Used, in good working condition.
