A2041(206X180X136Xmm, 2.8kg)

A2042(260X180X136, 3.2kg)

The A2041 and A2042 are electrodynamometer type and use the Taut-Band suspension and hair spring system. There instruments are highly reliable, and designed for use in laboratories for presistios measurement of power at DC and commercial frequencies up to 1000Hz. There instruments are housed in phenol resin cases and shielded with double permally sheets to block exteral magnetic fields.

Notes :

1. Forranges higher then 25A, use External Current Transformer with 2041 or2042 5A wattmeter.
2. For ranges higher than 240V, use External Potential Transformer.
