6 Watt Dual Output DC/DC Converter

Calex Mfg. Co., Inc. of Concord California announces the dual output HW family of DC/DC Converters. The series consists of nine models ranging from 5 watts to 6 watts of output power in an industry standard 24pin DIP. All models are fully self-contained with input and output filtering eliminating the need for external components in all but the most critical applications.

All HW models offer a 2:1 input range; 9 to 18VDC, 18 to 36VDC, or 36 to 75VDC. Outputs are ±5V, ±12V or ±15V. The current on the ±5V outputs are ±500mA. The ±12V and ±15V outputs offer ±250mA and ±200mA respectively. The converters are isolated input to output. Isolation voltage is 1544VDC. The switching frequency of all HW dual models is 400kHz. Efficiencies run as high as 83%.

Output noise is low at 1% of the output voltage as measured over a 20 MHz bandwidth. Cross regulation is ±1%. Initial setpoint accuracy is ±1%. Load regulation is also ±1%. Line regulation is ±0.3%. The operating case temperature range for the HW models is -40 to +100 deg C. The case size is 0.80" x 1.25" x 0.50"H. All models are backed by Calex's five year warranty.

Units are available from stock. Pricing is $26.95 (1000). For more information, contact Paul Cuff, CALEX Mfg. Co., Inc., 2401 Stanwell Dr., Concord, CA, 94520 web: www.calex.com email: sales@calex.com, ph: 800-542-3355 or 925-687-4411, fax: 925-687-3333.
