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. TECHNICAL NOTES Remote On/Off Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin and off during a logic low. To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the –Vin terminal. The switch can be an open collector or equivalent. A logic low is 0V to 1.2. A logic high is 3.5V to 12V. The maximum sink current at the on/off terminal (Pin 6) during a logic low is -500uA. Over Load 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. Over Voltage Protection The output over voltage clamp consists of control circuitry, which is independent of the primary regulation loop that monitors the voltage on the output terminals. The control loop of the clamp has a higher voltage set point than the primary loop. This provides a redundant voltage control that reduced the risk of output over voltage. Input Source Impedance The power module should be connected to a low ac-impedance input source. 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 a 12µF for the 12V, 4.7µF for the 24V input devices and a 2.2µF for the 48V devices, capacitor mounted close to the power module helps ensure stability of the unit. Output Ripple Reduction A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 3.3µF capacitors at the output. Maximum Capacitive Load This series has 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. See data sheet for maximum capacitance 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 100ºC. The derating curves are determined from measurements obtained in a test setup. 1/9/2018 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 6 DCMJW10 SERIES 10 Watts DC/DC Converter Single and Dual Outputs Rev B MODEL NUMBER SETUP DCMJW 10 Series Name Output Power - 24 S 12 HS R Input Voltage Output Quantity Ouptut Voltage - Heatsink Option Remote On/Off Option 12: 12VDC S: Single 033: 3.3VDC None: No Heatsink 24: 24VDC 05: 5VDC HS: Heatsink 48: 48VDC 051: 5.1VDC None: No Remote On/Off R: Remote On/Off HSR: Heatsink w/ Remote On/Off 12: 12VDC 15: 15VDC D: Dual 5: ±5VDC 12: ±12VDC 15: ±15VDC COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
