Molex header AC connections AC-DC LP-MD Preconfigured Models - Medical AC-DC LP & LP-MD Signals & Controls AC OK/Power Fail Global Inhibit When fitted in module position 2 of the chassis, pins 10 and 2 provide a minimum of 5 ms warning of loss of output regulation. Inhibiting the module fitted in position 2 will inhibit all outputs of other modules (fans remain running if fitted). If individual inhibit is required on the module fitted in chassis postion 2 alternative configurations are available. Please consult our application engineering team. 5V 330Ω AC OK (HIGH) Inhibit PIN 10 INTERNAL TO PSU (Open Collector) Pins 6 and 2 (return) provide on/off control of the module. Applying a logic ‘0’ between these pins turns the outputs off. PIN 2 AC NOT OK (LOW) OUTPUTS ON 5V OR FLOATING Current Share Connecting pins 4 & 2 of like part number modules (3 maximum) within the same chassis or separate chassis will force the modules to current share the outputs. 0V OUTPUTS OFF PIN 6 PIN 2 (Reverse logic option available, i.e. high for outputs off or low for outputs on). Module 1 Module 2 Module 3 Modules in Parallel Pin 2 Pin 4 Pin 2 Pin 2 Pin 4 Pin 4 Single output modules with the same part number and V1 of dual and triple output modules can be paralleled to obtain increased output current. These modules can either be fitted in the same chassis or a different chassis with their outputs connected directly together and current share connections made, see Current Share. DC OK Modules in Series Pins 8 and 2 provide notification that the output voltage is within regulation via a logic 1. Single output modules can be connected in series to obtain alternate output voltages not available from a single module. For example a 10 V (SG module) can be connected in series with a 12 V (S4 module) to obtain an output voltage of 22 V. 5V Remote Sense 330Ω DC OK (HIGH) PIN 8 INTERNAL TO PSU (Open Collector) DC NOT OK (LOW) Pins 1 (+ve) and 2 (-ve) provide compensation for voltage drops in application wiring up to a maximum of 0.5 V. Remote Sense is not fitted to (R) modules and V2 & V3 of (U) and (T) modules. PIN 2 Housekeeping (Reverse logic option available, i.e. high for DC NOT OK). Notes 1. (R) module does not have these signal facilities. A 5 V standby voltage rated at 1 A is fitted to each chassis.
