MSR-Electronic develops new products in the field of gas detection for power supply and water jet protection


MSR-Electronic from Pocking develops AP2-UPS battery backup power supply unit and WJP water jet protection enclosure.


In order to enhance the reliability and efficiency of power supply and water jet protection even further, MSR-Electronic has developed the AP2-UPS battery backup unit for uninterruptible power supply and the and the WJP enclosure for maximum water jet protection.


WJP enclosure

The WJP enclosure is compatible with all PolyGard® products  used with enclosure type C and offers them better ingress protection. Depending on the given installation, a rating of up to IP69K is achievable.

Several openings are provided on the sides of the WJP enclosure to ensure reliable gas detection and optimal flow. The black fittings prevent water ingress and egress through the openings. A cable entry plate with multiple ports is provided on the side of the enclosure and can be used in conjunction with the grey cable gland supplied with the product.

In addition, the housing has a transparent cover for detecting the visual warning by the WAO. In doing so, it serves in particular to improve the splash protection of products from the PolyGard® product series in housing type C. Due to its transparent, hinged lid, the housing is particularly convenient to operate.

Furthermore, the WJP enclosure can be individually adapted to any application. Since the housing also fulfills at least the IP protection class IP66, depending on the mounting even up to IP69K, it stands for complete contact protection and dust tightness. Thus, the housing protects against strong jets of water and is suitable for both indoor and outdoor use.


Akku-Package AP2-UPS

The battery package enables a battery-supported, uninterruptible power supply in a separate housing. The AP2-UPS uninterruptible power supply is used to ensure the power supply for up to 2 MSC2 multi-sensor controllers or 2 WSB2 warning and sensor boards in the event of disturbances in the power supply system, such as short-term power failures and power fluctuations in the form of overvoltage or undervoltage.

The devices of the PolyGard® product series are used for this purpose in conjunction with the UPS for monitoring and warning of toxic, explosive gases and vapors as well as Freon refrigerants in a wide range of gas measurement technology. In addition, the large number of freely configurable parameters and setpoints allows individual adaptation to many applications.


The UPS ensures that the power supply to the system is guaranteed in the event of overvoltages, undervoltages or power failures. Furthermore, the battery pack can be used for all small devices and controllers of the PolyGard® product series and even in smaller garages with small controllers it helps to meet the central standard of gas monitoring for garages and tunnels, EN 50545.
