Yokogawa 2558A AC Voltage Current Standard

The 2558A is a standalone solution for calibrating meters, clamps and CTs. With ranges up to 1200.0 V AC and 60.00 A AC mean that the 2558A is the instrument of choice for the cost-effective calibration of AC analogue meters. The unit can be intuitively operated via the front panel or controlled by an ATE system.
