178 Series | Hammond Manufacturing Transformers

Plug-In
178 Series Toroidal Isolation (120 VAC to 120 VAC)

Product Features
Primary 120 VAC, 50 / 60. Hz., Secondary 120 VAC. 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 (120 VAC to 120 VAC). Standard 3-wire, grounded plug (for use with adaptors for proper grounding). Input (primary) connected to a 5 foot long cord and standard North American plug (NEMA 5-15P). Output (secondary) connected to two standard - 3 wire grounded receptacles (NEMA 5-15R). Features include ventilated black steel case, rocker lighted on-off switch and circuit breaker protected output. North American Mark of Safety - C UL and 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 there high efficient Toroidal transformers.
