DY-KZ28-800-1
This product integrates discharge
circuit, charge circuit and shunt circuit to regulated five solar cell arrays
with combined array design. For each array, regulated capacity is 5A. For
discharge circuit, regulated capacity is 800W at the efficiency of 92%. This can
realize the follow-up charge for energy storage products.
DY-KZ28-2500-1
This product integrates discharge
circuit, charge circuit and shunt circuit to regulated ten solar cell arrays
with combined array design. For each array, regulated capacity is 10A. For
discharge circuit, regulated capacity is 2,500W at the efficiency of 88%. This
can realize the current Limit charge for energy storage products. The current
subject to this Limit is 0-20A.
DY-KZ28BS-4000-1
This product integrates discharge circuit, charge circuit and
shunt circuit. It consists of regulated bus and unregulated bus. The voltage of
regulated bus is 28V. Unregulated bus corresponds to H2-Ni and Li-ion
batteries, and its voltage can be adjusted to needs. Charge and discharge shunt
capacity can be expanded according to needs. The slave computer for power
source is employed to select 1553B bus or CAN bus according to needs.
DY-KZ42-3000-1
The control circuits S3R, BCR, BDR, TM/TC and MEA are
classified in terms of functional module, and arranged mainly in power control
unit. Moreover, it employs high accuracy PI integrated with MEA control
technology, and frequency limiting modulation for shunt, so as to modulate
multiple solar cell arrays. Meanwhile, it performs charge management and
accurate control of Li-ion battery. Power control unit employs the architecture
of modular integration to combine and expand S3R, BDR/BDR, BCR/BDR, TM/TC, MEA
and other modules according to general power. The bus interfaces for external
communications are optional.
