California Instruments

California Instruments, now part of Ametek Programmable Power, is a manufacturer of programmable AC and AC/DC power sources used in power electronics testing and compliance verification. Their programmable power supplies deliver a clean, stable sine wave output with precise frequency and voltage control, making them essential for simulating global mains conditions and testing equipment performance under a range of input scenarios. Units are programmable via GPIB, USB, and LAN interfaces, supporting automated test environments.

California Instruments power sources are widely used for IEC 61000, MIL-STD-704, and DO-160 compliance testing, where equipment must be verified against international and military power quality standards. Their CSW and AST series cover applications from benchtop development to high-power system-level testing of avionics and industrial equipment.

Key Product Lines

• CSW series — high-power programmable AC/DC power sources with regenerative capability for single and three-phase applications
• AST series — programmable AC power sources for avionics testing per MIL-STD-704 and DO-160
• Series II — compact single-phase programmable AC power sources for R&D and compliance labs
