Hammond Isolation Line Transformer is single winding, and for use where equipment is already isolated and only voltage change is required. Hammond Transformers support world wide applications, 50 or 60 Hz. operation, step up (115VAC to 230VAC). Hammond Line Isolation Transformer input is ABB Circuit Breaker protected. Hammond Transformers are Hi pot tested to 2 KV RMS Standard 3 wire, grounded plug (can also be used with adaptors for proper grounding). Hammond Transformer Input is connected to a 5 foot cord standard grounded North American plug (NEMA 5-15P).

Hammond Electronic Transformers use -1db roll off points to ensure a typical conservative rating, again at Full Output Power. To ensure a long life and maximum versatility these Hammond Transformer units are built to and tested at a Hi-Pot rating of 2,000 VAC. Our Hammond transformers are of EI laminated design, we do not offer toroidal designs due to their inability to handle tube imbalance and high manufacturing cost. More importantly, our designs are "ear tested". From Bach to rock and three watts to 280 watts, Hammond Manufacturing have your output transformer in stock.

Hammond Transformers Classic Tube feature enclosed (shielded), 4 slot, above chassis Type "X" mounting, both end bells include knockouts for optional above chassis wiring. Hammond Transformers frequency response is 30 HZ to 30 KHZ at full rated power. All Hammond Transformers Classic Tube units include a 40% screen tap for Ultra linear operation. These high quality Hammond Electronic Transformers Classic Tube units are also designed for maximum versatility.

New Single ended "universal" output Hammond transformers popular 125 series has two new additions (20 and 25 watt Hammond Manufacturing Transformer), Hammond classic tube transformers are optimized for single ended tube output circuits - the 125 SE series. Hammond Manufacturing is pleased to introduce a line of specialty control transformers ideally suited for general purpose, industrial, light duty loads.

Hammond Transformers are designed for applications where high inrush or machine tool duty, are not necessary, the SL series control Hammond Transformer offers an efficient and economical solution. These Hammond Transformer units are well suited for HVAC applications, signal and alarm systems, small motors, and lighting and circuit isolation. The SL control Hammond transformer is an open style unit with molded Entrelec Terminal Blocks, available with a full array of features including 10 fusing options, multiple primary and secondary voltages and optional clear plastic 'finger safe' terminal covers. For an economical approach for control Hammond transformers, the SL is the choice.

Hammond isolation transformers support primary 115VAC, 50/60 Hz., Secondary 95VAC. Hammond isolation transformers provide circuit isolation. Hammond Electronic transformers have electrostatic shield between primary and secondary. Hammond isolation transformers support world wide applications, 50 or 60 Hz. operation, step down (115VAC to 95 VAC). Hammond Manufacturing transformers are designed mainly for Japanese equipment in North America.

Hammond isolation transformers are perfect for operating "Classic" equipment that can not tolerate todays higher line voltages (ie..125 VAC input will produce a stress free 105 VAC output at full load PLUS isolation and shielding). Hammond isolation transformers Standard 3-wire, grounded plug (can also be used with adaptors for proper grounding).

Hammond isolation transformers are 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. Hammond isolation transformer features include ventilated black steel case, rocker lighted on-off switch and fuse protected output. These high quality Hammond transformers units are also designed for maximum versatility.

Hammond Transformers Constant Voltage AC Regulator protects against both brownouts and over voltage conditions. Hammond Transformers Constant Voltage AC Regulator protects against any power problem other than a blackout (Use a Sola UPS for blackouts). Hammond Transformer Constant Voltage AC Regulator will operate through a 3 millisecond (minimum) blackout. Hammond Transformer Constant Voltage AC Regulator Long life ferroresonant design no moving parts.

Hammond Transformer Constant Voltage AC Regulator ferroresonant design also filters out surges, line harmonics, and RF noise. Key features for series 153-159 Hammond DC Reactors or Filter Chokes include Economical "open bracket" channel mount, Tolerance of 15% on both inductance and resistance, Inductances measured at rated D.C. current, Minimum 5" long leads, and Hammond DC Reactors or Choke Filter units will exhibit less inductance at slightly higher currents or more at lower currents, and perfect for high voltage power supply filtering.
