    Emerson HD2475-2 rectifier module

    Emerson HD2475-2 rectifier module

    Rectifier module main function and characteristic

    1. Emerson HD2475-2 rectifier module soft switch
    Rectifier module power circuit is divided into active PFC correction and full-bridge DC / DC converter in two parts, full-bridge DC / DC converter using full-bridge phase-shifted soft-switching technology. The wide input voltage range (120V ~ 290V) and high efficiency (91%) are achieved, and the power density has reached the international advanced level.

    2. Emerson HD2475-2 rectifier module limited power control
    Rectifier module according to the input voltage and output voltage changes, the use of advanced limit power control method. When the input voltage in the 170 ~ 290VAC, the module can output high-power, when the input voltage of 120 ~ 170VAC, the module will use limited power control mode, so that the low input voltage to ensure that the load needs while ensuring the normal module Work, its output power and the relationship between the input voltage as shown in Figure 2-3.

    Figure 2-3 shows the relationship between the output power and the input voltage

    When the output voltage changes, the rectifier module will use limited power control, so that it can change in the larger output voltage range, the output power. The relationship between output current and output voltage is shown in Figure 2-4.

    Figure 2-4 shows the relationship between output current and output voltage

    3. Emerson HD2475-2 rectifier module short circuit protection
    Rectifier module uses advanced short-circuit protection to short circuit in the output of the case, the module output current retraction to a small value Isc (less than 1/3 rated current value Io), effectively protect themselves and external devices, When the short-circuit fault disappears, the module automatically resume work. Figure 2-5 shows the short-circuit recovery curve.

    4. Emerson HD2475-2 rectifier module hot-swappable
    Rectifier module using Emerson Network Power Company no damage hot plug patented technology (Patent No .: 99216547.4), the output and input are soft start and current limit device, when the module is inserted into the system, will not cause the system output voltage disturbance. Replace the module time is less than 1min.

    5. Emerson HD2475-2 rectifier module protection and fault alarm
    Rectifier module panel has three LED lights: power (green), protection (yellow), failure (red). When the input over-voltage or over-temperature module, the protection light; when the DC output over-voltage, module failure or fan failure, the fault light will light. These failures will be transmitted to the monitoring module, the monitoring module will receive the fault signal to make the appropriate treatment. Table 2-1 shows the response / operation mode of the rectifier module.

    Protection alarm, shutdown, can be automatically restored

    Over temperature

    Protection alarm, shutdown, can be automatically restored

    DC output overvoltage

    Fault alarm, shutdown, can not be automatically restored

    Module failure

    Fault alarm, shutdown, can not be automatically restored

    Fan failure

    Fault alarm, do not shut down

    6. Emerson HD2475-2 rectifier module low dropout autonomous current sharing
    Rectifier module using low-voltage differential between the autonomous current sharing technology, when the monitoring module or individual rectifier module failure, the remaining modules to maintain current sharing.

    7. Emerson HD2475-2 rectifier module without class current limiting technology
    The rectifier module adopts the infinite current limit technology. Under the control of the monitoring module, the current limiting point can be continuously adjustable between 0 ~ 110% of the rated current.

    8. Emerson HD2475-2 rectifier module monitoring and three remote functions
    Rectifier module has built-in CPU, monitoring and control module running, and is responsible for communication with the monitoring module. The rectifier module receives the parameter setting command such as on / off, current limiting, voltage setting and so on sent by the monitoring module through RS485, and realizes the voltage, current, temperature, current limit, on / off and alarm volume of the module in real time Reverse to the monitoring module to complete the monitoring module of the rectifier control module.

    9. Emerson HD2475-2 rectifier module fan control and dustproof
    Fan temperature control stepless speed, when the module temperature is below 40 ℃ when the fan is in a stall state (the earth to extend fan life), the temperature is higher than 40 ℃, the fan starts, the speed increases with the module temperature increases. The module alarms when the fan is open or shorted.

    The fan is fitted with a reusable air filter on the front.

    Fans, dust nets can be directly demolished by hand without shutting down the module. Fan replacement time ≤ 1min, air filter replacement time ≤ 1min.

    Above is the Emerson HD2475-2 rectifier module features and functions.
