The MSHU100 series requires a minimum output loading to maintain specified regulations. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications. 2. All DC/DC converters should be externally fused at the front end for protection. 3. Other input and output voltages may be available, please contact factory. *Due to advances in technology, specifications are subject to change without notice.

Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup. A capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100KHz) capacitor of 2.2μF for the 5V input models, a 1.0μF for the 12V input models, and a 0.47μF for the 24V input models. +Vin + DC Power Source - + +Out DC / DC Converter Load Cin -Vin + -Out +Vin Single Output DC / DC Converter DC Power Source - Wall Industries, Inc. 37 Industrial Drive Exeter, NH 03833 603-778-2300 www.wallindustries.com Fax 603-778-9797 +Out -Vin Cout Load -Out Page 4 of 8 MSHU100 Series 4000VAC I/O Isolation Single and Dual Outputs 2 Watt Medical DC/DC Converter Rev B Maximum Capacitive Load The MSHU100 series has a limit of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the startup time. For optimal performance we recommend 100μF maximum capacitive load for dual outputs and 330μF capacitive load for single outputs. The maximum capacitance can be found in the Model Selection Guide. TEST CONFIGURATIONS Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with an inductor Lin (4.7μH) and Cin (220μF, ESR < 1.0Ω at 100KHz) to simulate source impedance.

Current ripple is measured at the input terminals of the module. Measurement bandwidth is 0 ~ 500KHz. Peak-to-Peak Output Noise Measurement Test Use a Cout 0.47μF ceramic capacitor. Scope measurement should be made by using a BNC socket; measurement bandwidth is 0 ~ 20MHz.

To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 90°C. The derating curves are determined from measurements obtained in an experimental apparatus.
