Power-plus SystemPower-plus DC Power System is the latestinnovation modular DC power product offered byPower-plus Company, Inc.. Our Switching moderectifier power system is ideal for application such asprogram control switching systems, microwavedigital system, mobile phone switching system,industrial process control and emergency equipmentetc.

Our principal of design is to provide a range ofequipment’s in modular form which can be used asbuilding blocks for a vast range of system solutions.Added to this is the best design capability utilizingthe highly experienced resource from within ourengineering and development design teams.

Supplying some of the world’s major telecomscompanies with a wide range of standards andcustom designed products from its purpose builtfactory in Canada, Power-plus system are renownedfor its high reliability, which is clearly of majorimportance in power supplies for telecoms systems.

Our Products comfortably pass the most stringentdesign verification tests of manufactures. Utilizingprofession design facilities, we can offer rapidsolutions to power systems designs demanded by theworld markets for cellular radio, cable TV,telecommunications and safety critical systems.

High Quality Switchmode RectifiersOur major components are out Switchmode powerconverts operating from single phase mains ACpower supply or generators. They provide either anominal 12 volt, 24 volt or 48 volt output, dependingon type, and are specifically designed fortelecommunications loads and to maintain standbybattery sets fully charged. They are manufacturedunder ISO 9000 quality standard.

Every stage in manufacture is subject to thoroughinspection. Additionally, we have implemented anEMC strategy to ensure that our modules not onlycomply with current EMC standards, but in manycases far exceed the performance required. Pre-compliance testing is carried out using a combinationof in-house test equipment and special test laboratoryfacilities.

Self Contained SystemSystems comprising Switchmode/Thyristor rectifiersare completely self contained within a singleenclosed cabinet or mounting shelf (depends on thesize of the systems), which contains rectifiers, alarms/ controls, and MCB/ interface.

NOTES : * Provide Rectifiers of Modular and SCR-Thyristor as Automatic Battery Charger* Automatic Battery Charger can be designed up to 1000 Amps* Available DC Voltage for 100Vdc, 120Vdc and 125Vdc by request

Backup Time : Depends on the customer’s requirement

Output Current Limit : The system is designed to operate continuously in current limit. The current limitcharacteristic is constant down to 90 Vdc below which the current folds back to the shortcircuit value

Output Over Voltage : An output voltage in excess of the trip levels will cause the rectifier power to latch into ashutdown condition. The rectifier module can be reset by interrupting main input. The overvoltage trip is provided with discrimination so that on parallel connected rectifiers only thefaulty rectifier will be shutdown.

Thermal : A thermal sensor monitors the internal temperature of the rectifier module, which under thermal overloadconditions, will cause the unit to shutdown until the temperature has reduce to an acceptable level
