DCA ACA Clamp Adapter (CA-501) 200to400A For Digital Multimeters

Lutron CA-501 DCA/ACA Current Adapter (200A / 400A)

The Lutron CA-501 is a precision AC/DC current clamp adapter designed to extend the measurement capabilities of digital multimeters and voltmeters. Powered by a built-in Hall effect sensor, it accurately measures currents up to 400 A in both AC and DC applications.

Certified to ISO-9001 and compliant with IEC 1010 safety standards, this adapter is suitable for professional, industrial, and field diagnostic use.

Features

• Measures both AC and DC current up to 400A
• Two selectable ranges: 200A and 400A
• Outputs 1 mV per 1 A (AC or DC) for easy DMM integration
• Hall effect sensor for stable and accurate readings
• External DCA ZERO adjustment knob
• Wide AC frequency response (40–400 Hz)
• Compact, lightweight design (255 g including battery)
• Meets IEC 1010 safety standards

Specifications

Applications

• Use with DMM ACV 200 mV or 2V range to measure AC current
• Use with DMM DCV 200 mV or 2V range to measure DC current
• Current recording, indicators, controllers
• Precision clamp-on measurement for field diagnostics

Measuring Procedure

1. Determine the highest anticipated current (400 A or 200 A) using the appropriate range on the clamp adapter.
2. Insert the output plug (red or black) into the corresponding input terminal of the digital multimeter.
3. Set the multimeter to the AC 200 mV or AC 2 V measurement range, as required.
