The 4250A is a used Voltage Standard from Fluke. Engineers use direct current (DC) voltage standards to calibrate, standardize, normalize, and monitor drift, verify linearity, and establish regulation in electronic equipment. Standards are important during electronics compliance testing. Phase angle standards are ideal for calibrating many different electronics, including power analyzers, vector voltmeters, phase meters, phase sensitive instruments, and resolvers.

Additional Features:

  • Display: BCD
  • Current range: ±1A
  • Regulation: 0.001%

The 4250A Programmable Power Supply is a programmable power source which incorporates features not available in typical programmable power supplies: speed, accuracy, low programming noise, true current limiting, isolated control logic, output proportional to an external reference voltage. This power source can be operated in series or parallel. The 4250A is programmable in straight binary.
