Pulse Intros LP/14A/241/PC-10/ST Transformers

Pulse Engineering Inc. (San Diego, CA) announced a line of 50Hz/60Hz power transformers comprising six distinct series with more than 500 power, current and voltage combinations in both chassis and PC board plug-in mounting configurations. The PC board plug-in series (the LP, 14A, PC-10 and ST) feature a baked-resin finish that will withstand PCB-washing systems. Designed for maximum efficiency and high reliability, the products carry UL, TUV and CSA approvals. The products are used in power supplies of a wide variety of electronic and electrical equipment such as medical products, security systems and industrial controls.

The Low Profile Plug-in (LP) Series is available in three sizes from 2VA to 12VA in 14 output voltages ranging from 10 volts center tap (VCT) to 230VCT, providing semi-toroidal construction for reduced electromagnetic interference with a minimum of 1,500V isolation. Encapsulated, hermetically sealed models are available.

The Pulse International PC Plug-in (14A) Series is available in six sizes from 2.5VA to 56VA in seven output voltages ranging from 10VCT to 36VCT, featuring double-reinforced insulation. The dual-bobbin design provides a high primary-to-secondary isolation of 4,000V.

The Chassis Tran, Channel Frame-Mount (241) Series is available in six sizes, both single and dual primary, from 2.4VA to 100VA in 10 output voltages ranging from 10VCT to 120VCT. The devices have a high isolation of 2,500V to eliminate electrostatic shielding with an asymmetric design. The quick-connect terminals are also suitable for hard wiring.

The International High Power (A41) Series is available in five sizes from 25VA to 175VA in eight output voltages from 10VCT to 230VCT. The chassis-mount design features a dual bobbin with a high 4,000V, primary-to-secondary isolation.

The Concentric Vertical Mount PC Plug-In (PC-10) Series is available in five sizes, both single and dual primary, from 1VA to 24VA with 11 output voltages ranging from 10VCT to 230VCT, offering 1,500V isolation between primary and secondary. The transformers are compatible with industry-standard footprints.

The Split-Bobbin, Horizontal Plug-In (ST) Series is available in six sizes with both single and dual primary from 1.1VA to 36VA and 10 output voltages ranging from 10VCT to 120VCT, including a high-isolation, 2,500V model. With industry-standard footprints, the devices require no additional mounting hardware due to their rugged construction.

The new line of 50Hz/60Hz power transformers are available through distribution in moderate quantities, (100 to 249 pieces). Production lead-time is four to six weeks. Volume discounts are available. Each series' pricing varies according to configuration. Component pricing starts at $4.92 to $9.50 for the LP Series, $4.46 to $9.53 for the 14A Series, $3.86 to $11.98 for the 241 Series, $7.25 to $19.64 for the A41 Series, $3.42 to $6.60 for the PC-10 Series, and $3.69 to $7.03 for the ST Series.
