lineage power 9 data sheet april 2008 36 vdc to 75 vd c inputs; 20 w lw020 single-output-series power modules: design considerations grounding considerations for standard units, the case is connected internally to v i (+). for units with the case ground pin option, the case is not connected internally allowing the user flexi- bility in grounding. 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 mod- ule. for the test configuration in figure 11, a 33 f electrolytic capacitor (esr < 0.7 ? at 100 khz) mounted close to the power module helps ensure sta- bility of the unit. for other highly inductive source impedances, consult the fact ory for further application guidelines. safety considerations for safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., ul 1950, csa c22.2 no. 950-95, and vde 0805 (en60950, iec950). if the input source is non-selv (elv or a hazardous voltage greater than 60 vdc and less than or equal to 75 vdc), for the module's output to be considered meeting the requirements of safety extra-low voltage (selv), all of the following must be true: n the input source is to be provided with reinforced insulation from any other hazardous voltages, includ- ing the ac mains. n one v i pin and one v o pin are to be grounded or both the input and output pins are to be kept floating. n the input pins of the module are not operator acces- sible. n another selv reliability test is conducted on the whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module's output. note: do not ground either of the input pins of the module without grounding one of the output pins. this may allow a non-selv voltage to appear between the output pins and ground. the power module has extra-low voltage (elv) outputs when all inputs are elv. the input to these units is to be provided with a maxi- mum 5 a normal-blow fuse in the ungrounded lead. feature descriptions overcurrent protection to provide protection in a fault (output overload) condi- tion, the unit is equipped with internal current-limiting circuitry and can endure current limiting for an unlim- ited duration. at the point of current-limit in ception, the unit shifts from voltage contro l to current control. if the output voltage is pulled very low during a severe fault, the current-limit circuit can exhibit either foldback or tailout characteristics (output-current decrease or increase). the unit operates normally once the output current is brought back into its specified range. output overvoltage protection the output overvoltage clamp consists of control cir- cuitry, independent of the primary regulation loop, that monitors the voltage on the output terminals. the con- trol loop of the protection circuit has a higher voltage set point than the primary loop (see feature specifica- tions table). in a fault condition, the overvoltage clamp ensures that the output voltage does not exceed v o, clamp, max . this provides a redundant voltage-control that reduces the risk of output overvoltage. remote on/off two remote on/off options are available. 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, device code suffix ?1,? turns the module off during a logic high and on during a logic low. to turn the power module on and off, the user must supply a switch to contro l the voltage between the on/off terminal and the v i (?) terminal (v on/off ). the switch can be an open collector or equivalent (see fig- ure 14). a logic low is v on/off = ?0.7 v to 1.2 v. the max- imum i on/off during a logic low is 1 ma. the switch should maintain a logic-low voltage while sinking 1 ma. during a logic high, the maximum v on/off generated by the power module is 6 v. the maximum allowable leak- age current of the switch at v on/off = 6 v is 50 a.
