Auxiliary Functions
Adjustable Output Voltage (R input)
As a standard feature, the LOK units offer adjustable output
voltage by using the control input R. If the R pin is left open-
circuit, the output voltage is set to Vo nom. (see: Output data)
The R input is referenced to the secondary side of the
converter. Adjustment of the output voltage is possible by
means of either an external resistor or a voltage source.
a) Adjustment by means of an external resistor Rext1:
Depending upon the value of the required output voltage, the
resistor shall be connected
either: Between the R terminal and Vo– to achieve an output
voltage adjustment range of approximately
Vo = 90 - 100 % Vo nom.(LOK4301, 4601 and 4801 types)

or: Between the R terminal and Vo+ to achieve an output
voltage range of approximately Vo = 100 - 110% Vo nom for
rectifier versions and 100 - 125% Vo nom for battery chargers.

b) Adjustment by means of an external voltage Vext between
Vo– and R terminal to achieve an output voltage adjustment
range of approx. 90 - 110% Vo nom (LOK 4301, 4601 and
4801 types), 93 - 117% Vo nom for battery chargers.

Attempting to adjust the output below this range will cause
the converter to shut down (hiccup mode).
Note: Applying an external control voltage >3 V may damage the
converter.

Output Voltage OK (D Output)
The D-output is referenced to Vo– and monitors the output
voltage Vo. If Vo drops below Vo t, the D-output will be disabled
(open-collector circuit). The circuitry works independently of the
input voltage and can therefore be used as battery-low indicator.
Battery Charging/Temperature Sensor
The LOK 4140/4240/4740 are designed to charge lead-acid
batteries. For optimum battery charging and extended life time
of the battery an external temperature sensor may be
connected to the R-input. The sensor should be mounted as
close as possible to one of the poles of the battery.
Depending upon the cell voltage and the temperature coefficient
of the battery, different temperature sensors are available. For
more information please see: Temperature Sensors (Accessory
Products on the Web Site) or contact Power-One.
If no sensor is used, the float charge voltage should be
adjusted with a suitable resistor connected to the R input (see:
Adjustable Output Voltage).
