The PISA series protection module is an innovative low-cost product designed for current distribution and protection of 24V load circuits.
The PISA series protection module distributes the current from a large power supply across multiple low-current output channels, allowing for the use of thin wires. It also ensures that the unit's input voltage (corresponding to the power supply's output voltage) typically does not fall below 21V by limiting the output to a restricted current. Therefore, if high-sensitivity devices such as PLCs, controls, and sensors are directly connected to the same power supply as the PISA protection module, a stable supply voltage can be ensured. Loads that are not as critical (which are not affected by short-term voltage interruptions but could potentially lead to a failure of the 24V power supply) are connected to one of the four current-controlled output channels built into the PISA module. This provides protection regardless of the length of the wires or the characteristics of the power supply.
Integrating components around the power supply, such as AC inlet, switch, overcurrent protection, noise filter, and indicator lamp, to reduce total costs!!
This product is equipped with an AC inlet and noise filter in the Circuit Protector 3120 series. It consolidates up to 10 components into a single product. As a result, it is possible to integrate the following four functions into one: - ON/OFF rocker switch - Overcurrent protection function (circuit protector) - C14/C20 type inlet - Noise filter Furthermore, by consolidating these four functions into one, the following benefits are achieved: - Reduction in the number of components - Space-saving design - Reduction in assembly labor due to integration (up to 90%) - Reduction in component management costs These four reductions lead to overall cost savings. Additionally, the reliability of the entire device and system is improved.
Cost reduction through the reduction of the number of parts! Decreased after-sales labor costs for fuse replacement!
Replacement of conventional fuses with "circuit protectors" There is no need to select a large rated current (frame) to avoid startup current trips, allowing for miniaturization of PCB patterns. Since fuse replacement is unnecessary, design flexibility increases. The "Panel Mount Type 106 Series" and "Board Mount Type 1410-L2" consolidate the roles of fuse holder and fuse into one. The "3120 Series" combines four functions: a two-pole rocker switch, fuse, fuse holder, and harness into one, with the added inlet function in the "3120 + IEC Inlet Integrated Type." 【Benefits (partial)】 ■ No need for replacement fuses ■ Reduced after-sales labor costs for fuse replacement ■ No mistakes in the current rating of replacement fuses ■ No abnormal trips due to aging degradation like fuses ■ Miniaturization and reduced wiring through component integration *For more details, please download the PDF or feel free to contact us.
