C-Series: Low-Noise Switch Mode Power Supplies With User-Configurable Multiple Outputs
The C-series power supplies save design and production time and cost by allowing end-of-line selection of multiple output voltages to match alternative application circuit requirements, while using the same power supply base unit. DC voltage output modules are slot-mounted inside the base units to provide various combinations of single, dual, or parallel output voltages.

Safety
Observe the following points.
- *Read the Operation Manual and Detailed Specifications before use.
- *Observe the use conditions, environment, and cautions described in the documents.
Alarm signals
PR signal
This is an alarm signal provided for the main unit. When the input voltage to the main unit falls or the fan stops, the PR terminal becomes open.
LV signal
This is an alarm signal provided for the DC cell module. When the DC cell module output falls or stops, the LV alarm terminal becomes open.
Table 1 Alarm Specifications
Alarm | Conditions | |
---|---|---|
PR | Good | Low (0.8 V or less, 8 mA or less) |
Bad | Open(35Vmax) | |
LV | Good | Low (0.8 V or less, 20 mA or less) |
Bad | Open(35Vmax) |
Variable output voltage range, remote sensing, and remote ON/OFF control
Variable output voltage range
Each DC cell module has an output voltage adjustment volume knob. When the volume knob is turned clockwise, the output voltage rises. When changing the output voltage, do not exceed the rated output power, regardless of the rated output current. The output voltage variable range depends on the DC cell module. Check the specifications of the DC cell module before changing the output voltage.
Remote sensing
Some DC cell modules support a remote sensing feature. This feature compensates for a voltage drop caused by the output wiring. The compensation voltage value depends on the DC cell module. Determine the compensation voltage from the following table. Before using the remote sensing feature, perform sufficient evaluation and adjustment by referring to the connection example shown below.
Table 2 Remote sensing compensation voltage
Model | Voltage |
---|---|
C150S03, C150S05, C150S12, C150S15 | 0.15 V or less |
C150S24 | 0.30 V or less |
* Products not listed above do not support the remote sensing feature.
Note the following points when using the remote sensing feature.
- If a contact failure (such as loose screw) occurs in the load line, the load current flows into the remote sensing line, causing heat to be generated. This may damage the power supply. Pay careful attention to the connections.
- For the wiring between the power supply and the load, use a sufficiently thick wire for the output current and set the line drop to a value that is equal to or less than the specific compensation voltage.
- An oscillation waveform may occur in the power supply output voltage or the output voltage variation may become large due to the wiring or load impedance. Be sure to perform sufficient evaluation before use.
Figure 1 Example of remote sensing connection
Remote ON/OFF Control
The DC cell module has a remote ON/OFF control feature. This feature can turn on
and off the output voltage of any DC cell module according to the signal input to the
corresponding remote ON/OFF terminal.
Output of the corresponding DC cell module is stopped when a voltage of 10 to 27 V is
applied to the remote ON/OFF terminal. Inputting a voltage outside the specifications will
cause a malfunction or damage to the power supply. Be sure to use a voltage that falls within
the specifications. Note that the built-in fan of the main unit does not stop even when the
output of the DC cell module is stopped by using this feature.
The remote ON/OFF control feature is independent for each DC cell module. It cannot be used
to stop the output of all cell modules at once. To stop all the GND common slots at once,
connect the ON/OFF circuits in parallel.
* It is not possible to stop both the GND common slots and insulating slot at the same
time.
The remote ON/OFF auxiliary power supply can be used from AUX (CN1).
Use this for remote ON/OFF circuit operation.
* C650 has AUX1 and AUX2. Use AUX1 for the ON/OFF circuit of the DC cell module connected
to the GND common slots (slots 1 to 4). Use AUX2 for the ON/OFF circuit of the DC cell module
connected to the insulation slot (slot 5). Note that using these in different combinations
other than those above will lead to a power supply malfunction or damage.
