TMF 500A~3000A

Features

♦

Highly reliable Hall Effect device

♦

Compact and light weight

♦

Fast response time

♦

Excellent linearity of the output voltage over a wide input range

♦

Excellent frequency response (> 50 kHz)

♦

Low power consumption (16 mA nominal)

♦

Capable of measuring both DC and AC, both pulsed and mixed

♦

High isolation voltage between the measuring circuit and the

current-carrying conductor (AC2.5KV)

♦

Extended operating temperature range

♦

Flame-Retardant plastic case and silicone encapsulate, using

UL classified materials, ensures protection against

environmental contaminants and vibration over a wide

temperature and humidity range
