Original Press Release:
Quad Output DC/DC Converter
Calex Mfg. Co., Inc. of Concord, California announces the Model 70Q5.12SR 30 Watt Quad Output DC/DC Converter. The 70Q5.12SR has an input range of 40 to 120VDC and outputs of 5, 5, 12 and 12VDC. The outputs are isolated from the input and from output to output. Output to output isolation allows the connection of outputs in series to obtain higher output voltages, ie. 10V or 24Vout. The outputs can also be paralleled for increased output current. In general, the 5V and 12V outputs can be used in a variety of configurations for maximum flexibility.
The 70Q5.12SR is housed in a unique aluminum cast case with a built-in heatsink for improved thermal performance. The case size is 3" x 2.5" x 0.6"H. Four threaded through holes are provided in the case. With the integrated heatsink, thermal impedance is only 3.8°C case temperature rise per watt dissipated making the 70Q5.12SR ideal for thermally challenging environments. The case temperature operating range is -40°C to +100°C. The SR features thermal shutdown. The unit is protected by continuous short circuit protection with auto restart.
The output current on the 5V outputs is rated up to 1.4ADC each. The output current on the 12V outputs is rated up to 700mADC each. Output noise is 30mV peak to peak on the 5V outputs and 40mV peak to peak on the 12V outputs. Line and load regulation is ±0.2% and ±0.4% respectively for the 5V outputs. The line and load regulation for the 12V outputs is ±0.1% and ±.02% respectively. The switching frequency of the 70Q5.12SR is 225 kHz. The input to output isolation voltage is 1544VDC and the isolation from output to output is 200VDC. The SR also features trim and ON/OFF.
Pricing on the 70Q5.12SR is $83.30ea (1000). Units are available from stock. 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.
