S8V-CP

DC Electronic Circuit Protector (24 VDC 4 Outputs/8 Outputs Type)

S8V-CP

Simplified safety design of DC circuits Reliable DC circuit protection in the event of short circuits or overcurrent Saves space even with multi-channels Sequential start-up of outputs to avoid start-up trouble

Achievement for secure DC line protection when short circuit or over current state happen on DC 24 V line.

In accordance with the accelerating demand to the high power rating of the power supplies due to increased DC devices, you must meet a growing need for the safety design of each branch circuit and reliable protection to a circuit where abnormality occurs.

Facing any challenge in performing safety design of electric circuit?

Design

● Branch design and the design for securing the safety are complicated.
● Small diameter cables are preferable for easy wiring.

S8V-CP Features 5

Selection

● The selection is difficult as the tripping characteristics of thermomagnetic circuit protectors may widely vary by the temperature and unit variations.

S8V-CP Features 6

Assembly

● More branch circuits need more spaces.

S8V-CP Features 7

Start-up and Maintenance

● If an abnormality occurred, the power supply activates its protection function to stop the all circuits prior to the tripping function activation of the thermomagnetic circuit protectors.

S8V-CP Features 8

Replacement of the thermomagnetic circuit protector is easy

With maintaining the characteristics of the thermomagnetic circuit protector, make the variation errors less.

S8V-CP Features 9

An alarm signal output enables to output an abnormal occurrence to an upstream controller.

S8V-CP Features 10

Sequential start-up of branch circuits minimizes start-up troubles by the inrush current.

S8V-CP Features 11

The processes and costs for the UL certificate can be reduced.

What is the UL Class 2 output?

It is the classification that indicates “power supplies and the related products with safety outputs of which voltage, current, and power are limited to a certain level, so that not to cause an electric shock or fire,” and is evaluated by UL1310.
For the UL Class 2 output, the voltage, current, and power are provided as follows:

● DC30 V or lower of output voltage
● 8 A or lower of output current
● 100 VA or lower of output power

Any loads and parts to be connected to this UL Class 2 output can be used without UL certificate.

What is S8V-CP0424S (UL Class 2 output type)?

To meet the conditions of this UL Class 2 output, the rated output current is fixed at 3.8 A.

● 24 V of output voltage
 → meets DC30 V or lower
● 3.8 A of output current
 → meets 8 A or lower
● 24 V * 3.8 A of output power = 91.2 VA
 → meets 100 VA or lower

The processes and costs for applying to a safety standard for the devices can be reduced.

As S8V-CP0424S has already certified the UL Class 2 output, the UL evaluation of the circuit to be connected to this output is no need, meaning that helps reduce processes and costs for the UL certificate. Any loads and parts to be connected to this UL Class 2 output can be used without UL certificate.
Furthermore, that also helps for cost down and easy selection of the parts, because any wiring materials without UL certificate are usable in the control panel.
