| ( DataSheet : www..com ) 6 Watt Single Series DC/DC Converters Features ! ! ! ! ! ! Low Profile Copper Case (0.375" High) Six-Sided Shielded Case Low Input/Output Noise Operation 500 VDC Minimum Input to Output Isolation Output Overvoltage Clamp Fixed Frequency Operation Independent of Line and Load Highly Regulated/Low Drift Output Rugged High Speed MOSFET Power Chopper 5 Year Warranty ! ! ! Description These 6 Watt Single Output DC/DC converters are suitable for telecommunications and industrial control applications that call for direct PCB mounting. The converters in this series are designed with an LC input filter, a MOSFET push-pull power chopper, and an isolation transformer. A linear post regulator provides excellent line and load regulation. Noise is reduced by housing each unit in a six-sided shielded copper case. The CALEX 5 Year Warranty covers all converters in this series.

Refer to the CALEX Application Notes for the definition of terms, measurement circuits and other information. (2) Noise is measured per CALEX Application Notes. (3) Turn-on time is defined as the time from the application of power until the output is within 1% of its final value. (4) (5) (6) For long term short circuit protection of the converters, install a slow blow fuse in the input circuit. Choose a fuse size that is 125% of your applications actual input current and does not exceed 115% of the full load input current. No minimum load required. Short term stability is specified after a 30 minute warm-up at full load, and with constant line, load and ambient conditions. 2401 Stanwell Drive * Concord, California 94520 * Ph: 925/687-4411 or 800/542-3355 * Fax: 925/687-3333 * www.calex.com * Email: sales@calex.com 2 3/2001 6 Watt Single Series DC/DC Converters General Specifications* All Models Isolation Isolation Voltage 10A Leakage Input-Output Input to Output Capacitance Environmental Case Operating Range No Derating Units MIN TYP 700 75 -25 80 -40 85 -55 90 10 1.7 MS6, MS8, MS15 VDC pF MIN MAX MIN Case Functional Range (11) MAX MIN Storage Range MAX Thermal Impedance (12) TYP General TYP C C C C/Watt oz BOTTOM VIEW Mechanical tolerances unless otherwise noted: X.XX dimensions: 0.020 inches X.XXX dimensions: 0.005 inches Seal around terminals is not hermetic.

SIDE VIEW Unit Weight Chassis Mounting Kits After a 100% step change of the load, the output voltage will be within 1% of the final value within the transient response time. (8) Dynamic response is the peak overshoot voltage during the transient response time defined in note 7 above. (9) The input ripple rejection is specified for DC to 120Hz ripple with a modulation amplitude of 1% Vin. (10) For module protection only, see also Note 4. (11) The functional temperature range is intended to give an additional data point for use in evaluating this power supply. At the low functional temperature the power supply will function with no side effects, however sustained operation at the high functional temperature will reduce expected operational life. The data sheet specifications are not guaranteed over the functional temperature range. (7) Pin 1 2 3 5 Function +INPUT -INPUT +OUTPUT CMN (12) The Case Thermal Impedance is specified as the case temperature rise over ambient per package watt dissipated. (13) Input voltage range is 10.56 - 15.60 VDC when total output power is 3 watts or less. (14) Specifications subject to change without notice.
