The California Instruments 1251WP is a 1250 Watt AC Power Source designed to simulate world-wide line voltages and line frequencies.

The 1251WP features a universal line input that can operate from 100-240 Vac. The output voltage is switch-selectable for nominal values of 100, 115, 220, 230, & 240 VAC. Each voltage can be set for +/- 10% from nominal to simulate low or high line conditions. The output frequency is switch-selectable for 50 or 60 Hz nominal frequency and +/- 3 Hz from nominal.

The 1251WP is ideal for conformance testing of line-powered equipment that is required to operate from a variety of line voltages and frequencies.
