>Product Overview

EM330 series module UPS, power module 20/30KVA/3U, a single cabinet supports 10 power modules in parallel up to 300KVA, and 4 units can be connected in parallel between a single cabinet and a single cabinet to achieve a power of 1200KVA. Each power module has an independent DSP control unit, and in the event of a power module failure, it is automatically isolated from the system and the system can continue to operate.

Modular UPS uses a double-conversion in-line structure that includes rectifiers, inverters, chargers, control circuitry, input and output, and battery connector circuit breakers. input power factor compensation, etc. The modules are all hot-swappable online, providing a high level of availability and maintainability.

The failure of the control module will not affect the normal operation of the system. The control module can be hot-swapped and replaced online, and the parallel connection of the power module is also centrally managed by the control module, which runs in accordance with the unified parallel parameters, and the failure of a power module can automatically exit the parallel system, which will not cause harm to the entire parallel system. The parallel output voltage accuracy of the module is ±1%, and the parallel circulation current is <1% The static bypass module only contains the static switch of the bypass, and does not include the static switch of the main loop output, so when the static bypass module is replaced, it will not cause the system to be powered off or transferred to manual maintenance bypass, and the online hot swap replacement can be realized in battery mode.

Wide input frequency range: 40-70HZ, adapt to the harsh power grid environment, prolong battery life;

◇The number of battery cells is adjustable, support 30-40 batteries adjustable, when there is a battery failure, after taking out the faulty battery, the remaining battery can continue to backup power for the system:

◇Modular redundant spare parts design, no single point of failure;

◇The power modules all support online hot swapping, easy to expand and maintain, and the power supply, fan and important communication signals of the whole machine adopt redundant design, which is more reliable; ◇The output PF can reach 1, which is 1 1% more than the traditional UPS;

◇Decentralized control + centralized scheduling, the DSP in the power module is responsible for control, the energy control unit ECM is responsible for scheduling, the function is decoupled, and the logic complexity is reduced;

◇Centralized bypass design, the bypass module has built-in independent DSP control, can be plugged and repaired and replaced, and has strong impact resistance, avoiding the impedance imbalance between multiple low-power static bypasses.
