Signal Transformer Introduces "Machine Builder" Transformers for Heavy-Duty Machine and Medical Applications



Concentrically Constructed Platform Provides Double Reinforced Insulation and Volumetric Efficiency

Inwood, NY, - Signal Transformer, a subsidiary of Bel Fuse Inc. (NASDAQ: BELFA & BELFB), today announced the addition of the MTT (Machine Tool Transformer) "Machine Builder" Series of chassis-mount power isolation transformers to their expanding portfolio of standard and custom power transformers and high frequency magnetics. Offered to meet the highest reliability and performance requirements of today's commercial and heavy-duty machine applications, the six-part series' concentrically constructed platform provides double-reinforced insulation for the utmost in volumetric efficiency. MTT transformers feature leakage of less than 100 uA, and double-insulated windings to optimize reliability. The series is engineered to allow designers and installers to obtain 120V, 12V, and 24V output voltages from a single transformer powered directly by three-phase, three-wire distribution systems having no neutral leg. Notably, devices with dual primaries (DMTT) are supplied for applications requiring connections across 208V/240V or 420V/480V three-phase mains, as well as 220V to 240V single-phase feeds. A single primary part for 100V to 120V operation is additionally available. The transformers are dielectrically tested at 4000V between primary and secondaries. Secondary winding is completely isolated allowing the optimization of protection schemes for each. Top-mounted "touch safe" terminals are offered for protection.

Signal's new MTT "Machine Builder" Series is well suited for a broad range of voltage conversion applications in heavy-duty machinery, and mains isolation in medical equipment. Comprised of 300VA, 650VA or 1,000VA rated parts, the series is frequently specified to supply 120V for fans, lighting, PLCs (programmable logic controllers) and service receptacles, along with the 12V or 24V commonly needed for relays and controls. The new transformers incorporate a UL 1446 Class F (155 degrees C) insulation system to ensure reliable operation under harsh, industrial conditions, and comply with an array of domestic and international safety standards including UL 5085, UL 60601, IEC/EN 60950, and IEC/EN 61558.

Devices measure 4.12" (L) x 5.04" (W) x 3.86" (H) to 7.06" (L) x 5.1" (W) x 6.1" (H), and weigh from 9.82 lbs. to 33.5 lbs. Connections are IP-20 rated "touch safe" terminals offering screw/binding clamp for hard wiring, together with 3/16" and 1/4" Faston terminals.
