24v/48v DC Power System

General Details

24v/48v DC Power System Description

  1. 24v/48v DC Power System has two parts, one is PFC adjust; the other is DC/DC transformation.All technology make the wide input voltage range(85v-290v).
  2. High efficiency rectifier modules used soft switch technology, while load rate 10%, then efficiency can be 91%,50% load the efficiency can be above 96%
  3. Digital signal collection via an internal RS485 bus; RS232 interface for remote operation.
  4. Hot-swappable technology, plug and play, N+1 redundancy, extension slots. 24v/48v DC Power System using Low-pressure difference automatic current sharing technology between modules.
  5. EMI circuit provides a stable, reliable power to the load.24v/48v DC Power System adopted stepless current limiter technology, output current is continuously adjustable.
  6. Adopted stepless temperature control speed, it can reduce power consumption and prolong the life of the fan· Sharing load,equalized-current imbalance<3%.
  7. Optional Ethernet interface through SNMP and/or TCP/IP. Controller MCU·Fan use stepless temperature control to reduce losses and noise. Dual input AC and DC load power supply is reliable.
  8. Pairs of soft-switching technology and circuit topology. Dry contact alarm and out of the system function, more secure and more stable
  9. 2U height, 19 inch rack,light weight ,high power density. Active power factor compensation technology, the power factor is 0.9999.

24V rectifier module

  • The remote monitor signal output, simplify the monitoring difficulty.
  • With Auto equalized output in low-gap voltage of modules technology when the monitor module or individual rectifier is a failure the other modules can maintain current sharing. Distribution unit
  • shunt load with short-circuit and overcurrent protection, shunt capacity can be adjusted according to user requirements.
  • Battery input should connect with an external fuse protector or air switch, has a short circuit, over current protection and alarm functions, and can detect fault conditions.
  • safe operation: With the host computer own password and dual authentication, greatly protect system parameters safety.·Power off auto/manual, load off on/off control switch, etc.
  • Battery current, the total load current can be detected.
  • All DC outputs have fault detection function.
  • LVDS2 function to protect load and battery.
  • Capacity of MCB in each channel is 50A.

Communication protocol

  • Parameter setting is comprehensive, detailed: slave module time setting, temperature compensation setting, output over/low voltage setting, boost charge time setting,
  • over-voltage and recovery voltage setting, boost charge setting.
