Isolation - Step Down (240VAC to 120VAC) (289 Series) - Hammond Mfg.

Quality Products. Service Excellence.

Isolation - Step Down (240VAC to 120VAC)

289 Series

Plug-In

Features

Primary 240VAC, 50/60 Hz., Secondary 120VAC.

Provides circuit isolation.

Toroidal transformer for high isolation, low noise, light weight, cool operation and low

profile.

World wide applications, 50 or 60 Hz. operation, step down (240VAC to 120 VAC).

Standard 3-wire, grounded plug (for use with

adaptors

for proper grounding).

Input (primary) connected to a 5 foot long cord & standard 250V 2 pole, 3 wire - North

American plug (NEMA 6-15P).

Output (secondary) connected to two standard - 3 wire grounded receptacles (NEMA 5-

15R).

Features include ventilated black steel case, rocker lighted on-off switch & circuit breaker

protected output.

North American Mark of Safety - C UL & UL listed (File #E211544).

Indoor use only.

Remember

- These units do NOT convert line frequency.

Note about Inrush Current:

Due to the superior magnetic properties of Toroidal transformers they will be susceptible

to high magnetizing current when initially energized, only limited by the low DC resistance

of the primary winding. Depending on where you are in the AC cycle when the

transformer is energized dictates the chances of overloading the supply circuit. This is

why the transformer may sometimes energize without a problem and other times it will

blow the fuse or trip the circuit breaker. The duration of this overload is rarely longer than

a half of a cycle. Therefore, you should consider using a slow-blow fuse, time delayed

circuit breaker or other form of soft start circuitry for the supply line when using these high

efficient Toroidal transformers.
