(2) Refer to the CALEX Application Notes for information of fusing. For inrush current, refer to the specifications above. (3) 100F capacitor connected between the two "Input" terminals. Then insert current sensor in series with 1.0H inductor between 100F and the source. The reflected ripple current is measured over a 5 Hz to 20 MHz bandwidth. (current sensor is located between the converter input terminal and the 1.0 H inductor) (4) Optimum performance is obtained when this power supply is operated within the minimum to maximum load specifications. No damage to the module will occur when the output is operated at less than minimum load, however, below minimum load the dynamic response will degrade. Operation below minimum load is not recommended. (5) Load Regulation is defined as the output voltage change when changing load current from a 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 = 2s). (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 0.1F ceramic capacitor connected across the output terminals. Measurement bandwidth is 0-20MHz. (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 10A may be sufficient to trigger the ON/OFF to the logic-low state. 2401 Stanwell Drive, Concord Ca. 94520 (10) Most switches would be suitable for the logic ON/OFF control. In case there is a problem you can make the following estimations and then leave some margin. When open collector is used for logic high, "Open Circuit Voltage at ON/OFF Terminal", "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 Terminal", "Output Resistance" and "LOW Logic Level" are used to estimate the low impedance requirement of the switch. (11) Do not immerse in liquid. Converters are not hermetically sealed. (12) Input impedance on these units needs to be kept to a minimum. The 9-36Vdc DC units need a maximum input impedance of 0.135 Ohms and the 18-75Vdc DC units need a maximum input impedance of 0.54 Ohms. In order to support this requirement, the 9-36Vdc DC units need 55 F of capacitance (low ESR) for every 1.0 H of inductance between the power source and the DC/DC converter. The 18-75Vdc DC units need 3.5F of capacitance (low ESR) for every 1.0 H of inductance between the power source and the DC/DC converter. Inductance includes all sources and should take into account input power lines. (13) Specifications subject to change without notice.
