Shutdown
All CPS-EC units are featured with an external shutdown (switch/open collector).
When the connection is open the power-supply operates. When the
connection is closed the power supply goes into a standby mode
(short-circuited). The power supply powers up as soon as the shutdown
connections is opened. The signal through the connections is 1Vdc max. . The
shutdown connections have an internal pull-up resistor with 4700
Ω
at the plus
line (max. +12V inserted).
Boost Charge
The CPS-EC1500 features a boost charge mode (switch/open collector). When
the connection is open the power-supply operates the set current. When it is
closed (short-circuited) the power supply de10% current boost. The overall
power of 1500W cannot be exceeded. The boost charge is no power-boost, and it
is recommended to set the current limiting to
≤
90%.The factory set is 100%.
The boost charge releases as soon as the connection is opened. The signal
through the connection is 1Vdc max. . The boost charge connections have an
internal pull-up resistor with 4700
Ω
at the plus line (max. +12V inserted).
DC-OK (Power Good Relay)
The DC ok relay indicates if the output voltage is low and if the AC voltage is low.
The contact is galvanic insulated to the AC input and the DC output connections.
The isolation is 3000Vac with a forced isolation and covers the overall adjustment
range of the CPS-EC series up to 400Vdc. If the DC voltage is ok the relay is
closed, if the power supply unit is in false operation, in the shutdown or in the
inhibit mode, the relay is open. Considering the lower and the upper margin of the
AC voltage detection it is to say that the CPS-EC series starts at 150Vac. The unit
starts with 210Vdc when a DC voltage applies to the input.
The below table of values shows the hysteresis of the lower and upper threshold
margins where the DC OK Relay indicates a low voltage. The nominal voltage of the cell voltage of a typical
lead acid battery VRLA & vented GEL & AGM is listed (OPsZ, OPzS, OPzV, OGi, OGiV, GiV types).
WARNING!
Regarding the DC-output voltage setting range it is important to consider that this data sheet shows
the guaranteed values. In practice the range will be wider and with some models the lower margin of the setting
range will be below the DC ok high margin of the DC-ok relay. Make sure that the output voltage setting will
properly stay above the DC ok high margin to avoid false messages from the relay. ^
