Transient Recovery Time is measured to within 1% error band for a step change in output load of 75% to 100%. 2. Ripple & Noise measurement bandwidth is 0~20MHz. 3. These power converters require a minimum output loading to maintain specified regulation. Operation at no-load will not damage these devices, however they may not meet all listed specifications. 4. Other input and output voltages may be available, please contact factory. 5. To order the converter with Remote On/Off function, please add suffix ”-RC” (Ex: CMCG48S5-5000-RC). 6. Chassis Mount Options: No suffix for open frame, “U” suffix for U Channel, and “E” suffix for Enclosed type. Due to advances in technology, specifications subject to change without notice.

B CMCG Series 30 Watt Single Output 2:1 Input Voltage Range Chassis Mount DC/DC Converter DESIGN & FEATURE CONSIDERATIONS 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. Negative logic remote on/off turns the module off during a logic low and on during a logic high. 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 -0.7V to 1.0V. A logic high is 2.5V to 100V. The maximum sink current at the On/Off terminal (Pin 3) during a logic low is 100 mA. The maximum allowable leakage current of a switch connected to the On/Off terminal (Pin 3) at logic high (2.5V to 100V) is 5uA. Output Voltage Trim Output voltage trim allows the user to increase or decrease the output voltage set point of a module. The output voltage can be adjusted by placing an external resistor (Radj) between the Trim and +Vout or -Vout terminals. By adjusting Radj, the output voltage can be changed by ±10% of the nominal output voltage. A 10K, 1 or 10 Turn trimpot is usually specified for continuous trimming. Trim pin may be safely left floating if it is not used. Connecting the external resistor (Radj (up)) between the Trim and -Vout pins increases the output voltage set point as defined by the following equation: Radj( up ) = (33 ∗ Vout ) − (30 ∗ Vadj) Vadj − Vout Connecting the external resistor (Radj (down)) between the Trim and +Vout pins decreases the output voltage set point as defined by the following equation: Radj( down ) = Vout: Vadj: Units: (36.667 ∗ Vadj) − (33 ∗ Vout ) Vout − Vadj Nominal Output Voltage Adjusted Output Voltage VDC/KΩ 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.

B 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. Output 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 reduces the risk of output over voltage. The OVP level can be found in the “Output Voltage / Current Rating Chart.” 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 105°C. The derating curves are determined from measurements obtained in an experimental apparatus.

B CMCG Series 30 Watt Single Output 2:1 Input Voltage Range Chassis Mount DC/DC Converter TEST CONFIGURATIONS Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with an inductor Lin (4.7uH) and Cin (220uF, ESR < 1.0Ω at 100 KHz) to simulate source impedance. 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 Cout = 1.0uF 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. COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 40 years.
