ELCON PS1550 1550/PM-230 Module

As many as six power modules can be housed in the PS1550 system, any unused slot can be covered by panel. Each Power Module consists of an insulated DC/DC converter, which functions in switching mode at a frequency of 330 KHz. LAMBDA PH150S-280-24 for type-230 and LAMBDA PH150S-110-24 for type-115 components are utili - zed: they convert the rectified power supply current present in bus +IN / -IN, into 24 V voltage output.
A filtering stage is present at input of all Power Modules which permits the reduction of conducted emissions.
The bus output connection is carried out by a low drop diode which acts as an insulator in case of breakdown or fai- lure.
Each of the Modules is sized (for reasons of heat dissipation and reliability) to deliver up to 6A nominal but can also funish up to 7 A before creating an alarm situation (it is possible to set this threshold via trimmer RV2, factory set). When overloaded the current is limited to about 8 A.
There are four test points on front panel which permit current and voltage output readout of specific Module: these points present an output resistance of 1 Kn.
The measure of voltage at test points is greater than that measured in Module output due to drop in decoupling dio- de (typically 0.4 V).
To get a readout of current furnished by Module via dedicated test points, utilize predisposed tester as a continuous voltmeter ; every 100 mV detected correspond to 1A of delivered voltage (for example 560 mV correspond to 5.6 A). The measurement signal is obtained simply by amplifying by LM 385 the voltage drop in shunt.
