4:1 Ultra Wide Input Voltage
See data sheet

Polytron Devices, Inc. has recently released for mass production a complete line of 3 Watt DC/DC converters in a SIP package (0.86” X 0.36” X 0.44”) This “SWB3” series boasts high efficiency of 82% and on/off control flexibility. These converters are encapsulated and operate without de-rating over their full specified temperature range.

This series is available with a 4:1 input voltage range as follows:
9-36Vdc and 18-72Vdc. Single and Dual output voltages are available as follows: 3.3, 5, 9, 12, +/-5, +/-12, +/-15Vdc.

Pertinent specifications include: continuous short circuit protection and 1600Vdc Isolation. These units are designed for a variety of applications including : wireless network, telecom/datacom, industry control system, measurement and semiconductor equipment. All units are 100% burned in under full load, hi pot tested and final electrical tested prior to shipment.

This series of converters is competitively priced at $19.75 at 1000 quantity.
Average lead time is 4-5 weeks.

Other features include:

All specifications are typical at nominal input, full load, and 25 degrees unless otherwise noted.

INDUSTRIAL/AUTOMOTIVE POWER SUPPLIES
60 Watt Wide Input Range

POLYTRON DEVICES, INC. has recently released for mass production a product line of 60 Watt Automotive/ Industrial DC/DC converters housed in a 6" X 3" X 1.7" package. This convenient package is sold with input/output heavy duty cables and is totally enclosed in an environmentally sealed heavy duty aluminum case with a weather proof switch. (Cables are also available separately.) This series, designated "AICP, is designed for any applications exposed to rugged environments including heavy duty industrial and automotive applications. Specific applications include: Heavy duty forklift computers, nautical navigation systems, nautical computer systems and much more.

These power supplies operate without derating or heat sinking over their full specified temperature range . This series is available with 12Vdc out with input voltages as follows: 9-36Vdc Input, 16-72Vdc Input and 36-72Vdc Input. Other input and output voltages are also available.

Pertinent specifications include: input filter, short circuit protection and high efficiency (up to 85%) All units are burned in under full load, hi-pot tested and final electrical tested prior to shipment.
