VPM – Series Medical Grade Transformers

Triad Magnetics has extensive experience in manufacturing medical grade transformers. Triad’s Toroidal Medical power transformers are ideal transformers for a range of medical applications and, with more than 45 models available, we have a transformer for each of them. Our toroidal construction medical power transformers, with dual secondary cores to allow for both series and parallel connections, maintain low leakage current, low stray fields, regulation between 0.7% and 12.3%, and low temperatures rises of only 25ºC to 55ºC. VPM-Series Power Range: 25VA to 10KVA Primary: 100, 120, 208, 220 or 240VAC, 50/60Hz Secondary: Dual for parallel or series connection Insulation Class: Class F, 155°C Dielectric Isolation (Pri to Sec): 4KV for 60 secs. Low leakage current and low stray field.

Pulse Transformers

Pulse transformers are specially designed, common mode chokes that filter out any common mode EMI currents coming from the power line communication’s power transformer or the analog front-end of the modem. With support for up to 264 VAC and low insertion loss starting at 1 MHz, pulse transformers are an effective solution to pass EMI regulatory compliance, while allowing the desired signals to pass unaffected.


Triad chassis mount World Series Toroidal transformers are efficient, compact, cool running and cost effective. They are approved to UL 506 and CE IE C 61558-1 and 615 58-2-6, and are constructed with a Class B (130C) rated insulation system. These toroidal transformers have minimal stray fields for quiet operation around sensitive circuits. The transformers consist dual primaries and dual secondaries which allows for flexibility in the input and output voltages. The primary and secondary are both electrically isolated from each other and from the core itself . Chassis mount Toroidal World Series transformers are available in sizes ranging from 25 VA to 2,500 VA and are equipped with leads for connections.


Triad chassis mount World Series transformers are designed to meet U.S. and International standards including CSA, IEC, TUV and UL requirements. The transformers consist of a dual bobbin design positioned inside an insulating shroud and constructed with UL approved high temperature material. This design eliminates the need for electrostatic shielding since there is minimal capacitance between coils when using a dual bobbin configuration. The primary and secondary are both electrically isolated from each other, and from the core itself. Chassis mount World Series transformers are available in sizes ranging from 25 VA to 175 VA, and are equipped with convenient “quick connect” terminations.


Triad control transformers come with tamper resistant shrouds for safety and steel bracket welded to the bottom of the transformer for ease of mounting.

The Triad Split Pack™ split bobbin transformer is an extremely versatile tool for PC board applications. Split Pack™ transformers are nonconcentrically wound – with primaries and secondaries side-by-side. Unlike the secondary-on-top-of-primary designs of standard PC board transformers, the split bobbin winding and low capacitive coupling eliminate costly electrostatic shielding. It is offered in a dual secondary configuration with either single or dual primaries.
