Hammond Plug-In Isolation Transformers
Hammond isolation transformers provide complete circuit
isolation to protect your sensitive electronics. 171E features an
electrostatic shield between the primary and secondary which
greatly attenuates surges and noise caused by power problems
on the same circuit or by supply disruptions from utilities. Iso-
lation transformers are an essential for laboratory test benches
where line voltage is used.
For safety concerns, every 171E has been hi-pot tested to 2KV
RMS, and features a 5 amp circuit breaker on the primary. The
primary features a 5’ cord with a standard NEMA 5-15P plug.
The secondary is connected to a 1’ cord with a standard NEMA
5-15R receptacle. All units carry the North American mark of
safety C UL & UL listed (File # E211544).
