| 75 Watt HE Single Series DC/DC Converters Features ! Small Size 2.4" x 2.28" x 0.55" ! Industry Standard Pinout ! Excellent Thermal Performance with Metal Baseplate ! High Efficiency ! Volt-seconds Clamp and Fast Over Voltage Clamp ! Pulse-by-pulse Current Limiting, Short Circuit ! ! ! ! ! Description The 75 watt single HE series DC/DC converters provide precisely regulated dc outputs. All outputs are fully isolated from the inputs, allowing the output to be used with positive or negative polarity and various grounding options. The HE series meets the most rigorous requirements in an industry standard case size for industrial process control and telecom applications. Standard features include remote sensing, output trim, and remote on/off. Threaded-through holes are provided to allow easy mounting or to add a heat sink for extended temperature use. ! ! ! ! ! ! ! ! ! ! !

(2) 33 F capacitor connected to two "Input" pins. Then place current sensor in series with 12 H inductor between 33 F and source. The reflected ripple current is measured over 5 Hz to 20 MHz bandwidth. (3) Refer to the CALEX Application Notes for information on fusing. (4) Optimum performance is obtained when this power supply is operated within the minimum to maximum load specifications. No damage to module will occur, when the output is operated at less than minimum load, but the output voltage may contain a low frequency component that may exceed output noise specifications. (5) Load regulation is defined as the output voltage change when changing load current from maximum to minimum. (6) Load Transient Recovery Time is defined as the time for the output to settle from a 50 to 75% step load change to a 1% error band (rise time of step = 2Sec). (7) Load Transient Overshoot is defined as the peak overshoot during a transient as defined in the Note 6 above. (8) Noise is measured per the CALEX Application Notes. Output noise is measured with a 10F tantalum capacitor in parallel with a 0.1 F ceramic capacitor connected across the output to CMN. Measurement bandwidth is 0-20 MHz. (9) When an external On/Off switch is used, such as open collector switch, logic high requires the switch to be high-impedance. Switch leakage currents greater than 10 uA may be sufficient to trigger the ON/Off to the logic-low state. (10) Most switches would be suitable for logic On/Off control, in case there is a problem, you can make following estimations and then leave some margins. When open collector is used for logic high, "Open Circuit Voltage at On/Off Pin", "Output Resistance" and "External Leakage Current Allowed for Logic High" are used to estimate the high impedance requirement of open collector. When switch is used for logic low, "Open Circuit Voltage at On/ Off Pin", "Output Resistance" and "LOW Logic Level" are used to estimate the low impedance requirement of switch.
