Kesta UPS Power YDE9101H Kesta UPS Power 1000VA Long -Effect Model 1K 24VDC

Product performance

■ Advanced working mode

· Dual conversion online design makes the UPS output a pure sine wave power supply that is frequency tracking, phase-locking and voltage stabilizing, filtering out noise, and not being disturbed by power grid fluctuations, providing more comprehensive protection for the load.

· Output zero conversion time, meeting the high standard requirements of precision equipment for power supply.

· Using input power factor correction (PFC) technology, the input power factor is higher than 0.99, which improves the power utilization rate, greatly eliminates the harmonic pollution of UPS on the mains power grid, and reduces the operating cost of UPS.

■ DSP full digital control

· Used digital control, excellent performance indicators, avoiding the risks brought by analog device failure, and making the control system more stable and reliable.

■ Economic Operation Mode (ECO) function

· When the input mains power is within a fixed range, the input mains power is directly supplied to the load, and the inverter is in a waiting state; when the input mains power is abnormal, it is immediately converted to the inverter power supply.The ECO operating mode can be efficient and energy-saving, reducing user usage costs.

■ Optimized battery pack functional design

· Through innovative optimization of battery pack functional design, whether it is a standard model or a long-delay model, it saves battery usage more than traditional design solutions under the same backup time conditions.

■ Strong environmental adaptability

· The wide voltage range can avoid frequent switching to battery power when the grid voltage changes greatly, and adapt to areas with harsh power environment.

· Wide input frequency range, ensuring stable operation of various fuel generators when connected to them, meeting users' requirements for oil engine use.

Reliable protection function

·  has a self-diagnosis function for power-on, which can promptly detect hidden faults of UPS and prevent problems before they occur.

·  has various protections such as input over-voltage protection, output over-current, overload, short circuit protection, PFC and inverter overheating protection, battery overcharge and under-voltage warning protection, etc., to ensure the stability and reliability of system operation.

·  has automatic bypass function. When the output is overloaded or failed, it can be transferred to the bypass working state without interruption and will continue to supply power to the load.

·  has DC startup function, which can directly start the UPS without mains power to meet the user's emergency needs.

■ rich options, intelligent management

· Chinese LCD LCD interface can display load capacity, battery capacity, input and output parameters and fault information, making it convenient for user operation and maintenance management.

· Optocoupling dry node.Through the DB9 dry node interface, the main abnormal information of the UPS can be drawn out through the dry node, and the dry node signals are isolated by optical cores. Users can easily use these signals to control some strong and weak current devices.

· SNMP card/centralized monitoring card (optional accessory).The optional SNMP card can be connected to Ethernet to enable remote monitoring.The centralized monitoring card can realize simultaneous monitoring of multiple machines, recording events and alarms occurring in each machine.The SNMP card/centralized monitoring card is a gold finger card structure, and users can invest in installments and purchase it when needed.

· Alarm relay card (optional accessory).Up to 6-channel alarm relay output provides a large capacity interface to facilitate users to connect to extended alarm devices.

·  parallel interface module (optional accessory).Through the optional parallel machine interface module, four machines can be powered in parallel.

■ Fault isolation

· The maintenance bypass module can be separated. When the UPS fails and needs repair, the maintenance bypass module can be removed online, and the output load can be maintained continuously.
