The LAN K series requires a 10% minimum load on the output to maintain specified regulation. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications. All DC/DC converters should be externally fused at the front end for protection.

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. 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 100 KHz) capacitor of 8.2µF for the 5V input devices, a 3.3µF for the 12V input devices, and a 1.5µF for the 24V and 48V devices. + DC Power Source - +Vin + +Out DC / DC Converter Load Cin -Vin -Out Maximum Capacitive Load The LAN K series has a limitation 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 optimum performance we recommend 1000µF maximum capacitive load for dual outputs and 4000µF capacitive load for single outputs. Over Current Protection To provide protection in a fault (output over load) condition, the unit is equipped with internal current limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specific range. 3/11/2016 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: [email protected] Page 5 of 7 LAN K SERIES 2~4 Watts DC/DC Converter Single and Dual Output Rev D 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.

To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 90ºC.
