California Instruments 2750L

3KVA AC Source
Contact us for pricing and availability.
The L Series consist of a range of AC Power Source products with output power levels from 833 VA to 30 kVA. Using high frequency PWM technology, these units provide precision AC power in single, dual (split) or three phase configurations. All L Series units use dual voltage ranges and programmable current limits to protect the unit under test. Standard voltage ranges of 135 and 270 Volt rms are typical but optional output range options offer voltage ranges up to 400 V rms. The complete solid state, high switching speed PWM architecture of the L Series ensures low noise and low distortion output over a wide range of power levels.
