DC48V / DC24V 30A high-frequency switching power supply rectifier module adopts advanced two-transistor forward switching technology, the use of isolation between the modules to prevent mutual influence between modules, in the case of N + 1 backup, even if there are one or several modules failure does not affect the operation of other modules in parallel; inter-module enables automatic current; header type module three and a half meter display, display output current and voltage, simple and practical. Module width of 19 ", height 2U standard chassis, easy to install technical parameters of the project measurement conditions MIN TYP MAX Unit Input voltage range Output 24V / 30A 40 48.0 60 V power surge input 48V, loaded with 25 A output 48V input voltage range , 26.7 V Output Current Input 48.0V, 26.7V 30.0 31 Adc output output current limit input 48.0V 31 A load regulation input 48V, output 5% to 100% full load regulation of 0.5% Power input 40 ~ 60V Output 24V / 30A 0.1 0.1% telephone balance weight noise input 48V, output at full load 300 ~ 3400HZ 2 mV peak bee a noise input 48V, output at full load 0 ~ 20MHZ 100 mV broadband noise input 48V, output 24V / 30A 3.4 ~ 150KHZ 50mV 0.15 ~ 30MHZ 20mV discrete noise input 48V, output 24V / 20A 3.4 ~ 150KHZ 5mV 150 ~ 200KHZ 3mV 200 ~ 500 KHZ 2mV 0.5 ~ 30MHZ 1mV efficiency input 48.0V, 85% of full load Dynamic Response 20% to 100% step load 100us 80 ~ 150 V step Power 100us Input protection (output 50% load) Overvoltage protection, shut off the output 60 V power grid is normal, restore output 56 V output overvoltage protection Overvoltage protection, shut off the output 30.0 V temperature coefficient input 48.0V, output full load 0.0002 1 / ℃ operating temperature above 40 ℃ is 50% of full load -10 +50 ℃ Storage temperature -40 +85 ℃ MTBF 100,000 hours Weight 7.0 Kg Protection 1. Enter undervoltage protection grid voltage large fluctuations, to prevent long-term work in the low-voltage module or the case of high-voltage leads to shortened life or damage to the module, the module has an input over-voltage protection circuit, there have been automatically locked after a Brown modules, grid voltage is normal, the module can automatically return to work. 2. Output overvoltage Output voltage is too high to protect electrical equipment can cause catastrophic accidents, is to prevent such occurrences, over-voltage protection circuit within my company's high-frequency module, appeared output over voltage module automatically locked after the corresponding module fault indicator light fault module automatically deactivated without affecting the normal operation of the entire system. 3. Output current limit protection for each module's output power is limited, the output current can not grow indefinitely, so each module maximum output current is limited to the rated output current 1.05 times, if overloaded, the module automatically reduce the output voltage to protect the module. 4. Short-circuit protection rectifier output characteristics shown in Figure 2, when the output short circuit module in an instant the output voltage down to zero, to limit short-circuit current limit point of next, the module output power is very small, in order to achieve the purpose of the protection module. Modules can be long-term work in a short circuit condition, not damaged, troubleshooting module can automatically return to work. 5. modules in parallel to protect every internal protection circuit modules are connected in parallel, the absolute guarantee that the faulty module automatically exit the system without affecting other normal module. 6. Over-temperature protection over-temperature protection is primarily to protect power converter device, the junction temperature and current overload these devices are safe limit, under normal operating conditions, the system designed to leave sufficient margin, in some special circumstances, If the ambient temperature is too high, lower the fan stops, etc., the module detects heat sink temperature exceeds 75 ℃, automatic shutdown protection, the temperature decreased to 65 ℃ when the module starts automatically. 7. overcurrent protection overcurrent main power converter device in each cycle of the converter, if the current exceeds the device withstand current through closed power devices, to protect the power device purposes. Overcurrent protection can be automatically restored. Measurement function can automatically measure module and the module output voltage and current working status, and through the LCD display, the user can intuitively easy to understand modules and system status.
