DC POWER-S / SD — modular DC power systems
Country: Spain · Model: DC POWER-S / SD
The modular DC power systems DC POWER-S / SD are assembled from rectifier modules of 1000, 2000 or 2700 W and DC/DC modules of 900–2700 W. The output voltage from 24 to 220 V DC covers both telecom buses and substation control power.

Description
The system works as a source of operating direct current with a battery in buffer mode. The controller monitors the battery state, controls charging and distributes the load between modules and output lines. Up to 4 modules take 2U in a 19-inch rack, so a system of several kilowatts fits into an ordinary telecommunication cabinet. Up to 30 rectifiers work under one controller, and the power is increased by installing new modules without replacing the cabinet. If one module more than the load requires is installed, the failure of one module does not stop the power, and replacement is done on the fly. DC/DC modules form a second voltage from the same bus, for example 24 V for automation from a 48 V bus.
How to choose
The voltage is chosen by the consumers. For communications 48 V is usually taken, for relay protection and circuit breaker drives at substations 110, 125 or 220 V DC, and for automation 24 V. The 2700 W modules give the highest power per 2U. For currents of hundreds of amperes and thyristor charging of large stationary batteries, DC POWER-L / L 12P of 10–800 A is more appropriate, and if 230 V AC must be obtained from the batteries, the system is complemented with CS WAVE MDL inverters.

FAQ
What output voltages does the DC POWER-S have?
The systems are made for 24, 48, 60, 110, 125 and 220 V direct current.
How many rectifiers can be connected to one DC POWER controller?
Up to 30 rectifier modules work under one controller, which gives a reserve for system expansion.
What is the power of the DC POWER-S rectifier modules?
The rectifiers are 1000, 2000 or 2700 W, and the DC/DC modules 900–2700 W. Up to 4 modules are installed in 2U of a 19-inch rack.
Does the DC POWER-SD system monitor the battery state?
Yes, the controller monitors the battery, controls its charging and distributes the load between modules.
