General Details
24v/48v DC Power System Description
- 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).
- 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%
- Digital signal collection via an internal RS485 bus; RS232 interface for remote operation.
- 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.
- 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.
- Adopted stepless temperature control speed, it can reduce power consumption and prolong the life of the fan· Sharing load,equalized-current imbalance<3%.
- 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.
- Pairs of soft-switching technology and circuit topology. Dry contact alarm and out of the system function, more secure and more stable
- 2U height, 19 inch rack,light weight ,high power density. Active power factor compensation technology, the power factor is 0.9999.
Features
48V rectifier module SET1648
- When load rate is 10%, efficiency can reach 91%; when load rate is 50%, efficiency can reach above 96%.
- Active power filter technology highly reduces reflected noise.
- Small size, light weight, high efficiency and low noise.
- Over/low voltage protection, over current protection, short-circuit protection through sound and light alarm·Stepless current limiting technology, output current is continuously adjustable.
- Adopt stepless temperature control automatic speed adjustment, reduce power consumption and extend the life of the fan.
- Sharing load,Equalized- current imbalance≦3%
- 2U height, light weight, high power density
- High conversion efficiency
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.
