Specifications typical at +25°C, resistive load, nominal input voltage, rated output current unless otherwise noted. Transient Recovery Time is measured to within 1% error band for a step change in output of 75% to 100%. Ripple and noise measured at 20MHz bandwidth. The JC Series requires a 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. 5. All DC/DC converters should be externally fused on the front end for protection. 6. Other input and output voltages may be available, please contact factory. 7. Specifications 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. By using a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100kHz) 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. A capacitor mounted close to the power module helps ensure stability of the unit. Maximum Capacitive Load The JC Series has a limitation of maximum connected capacitance on the output. The power module may operate in current limiting mode during start-up, affecting the ramp-up and the startup time. The maximum capacitance can be found in the “Output Voltage / Current Rating Chart.” Over Current Protection To provide protection in a fault (output overload) 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 unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specified range. Thermal Considerations Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module, and board spacing. 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.

Capacitor Cin offsets possible battery impedance. Current ripple is measured at the input terminals of the module. Measurement bandwidth is 0-500 KHz. Peak-to-Peak Output Noise Measurement Test Use a Cout 0.47uF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20MHz. Position the load between 50mm and 75mm from the DC/DC Converter.

To reduce output ripple, it is recommended to use 3.3uF capacitors at the output. COMPANY INFORMATION: Wall Industries, Inc. has created custom and modified units for over 40 years.
