SCT-2420-220 Marine Charging Power Supply:

SC series marine power supplies are switch-mode charging power supplies applying high-frequency PWM pulse-duration modulation technology and mainly composed of IGBT, fieldeffect power tube and integrated PWM controller. The complete machine adoptsintelligent cooling.The reliable operation of power supplies can be ensured even in the hottest cabin. Power supplies meet all specifications and rules of China Classification Society, comply with the basic standards of marineelectric andspecifications, pass Type Approval of China Classification Society.and accord with the relevant regulations of GB7061 -98 General Specification for Low-Voltage Switchgear and Controlgear Assemblies in Ships "GB /T14548 93 General Specification for Marine Semiconductor Convertors and Rules for Classification of Sea-going Seel Ships

Range of input voltage:

Range of Voltage Input" indicated in the product manual refers to the range of normal operating voltage under the condition of ensuring all performance indicators of power supplies. The power module will encounter unstable performance or be damaged if input voltage exceeds this range.This kind of phenomena should be avoided.

Output power and heat emission conditions:

The output power of power supplies refers to output power in the case of meeting certain heat emission conditions. Maximum operating temperature generally refers to maximum ambient temperature (or shell temperature) under the condition of leaving enough heat emission space (Air inlet and outlet have a space of no less than 200mm) around power supplies and ensuring the performance indicators of power supplies. Forced ventilation should be applied to the installation environment when necessary.

In general, the ambient operating temperature of power supplies in the absence of heat emission is 20 to 40'C lower than the normal maximum operating temperature of power supplies, which depends on season and output power of power supplies. When using products, customers are advised to adopt the method of corresponding derating according to output power and heat emission conditions to prolong the service life of products.
