This buffer unit is a supplementary device for DC 24V power supplies. It delivers power to bridge typical mains failures

or extends the hold-up time after turn-off

of the AC power. In times when the pow

supply provides sufficient voltages, the

buffer unit stores energy in integrated

electrolytic capacitors. In case of mains

voltage fault, this energy is released again

in a regulated process. One buffer module can deliver 20A additional curren

The buffer unit does not require any control wiring. It can be added in parallel to

the load circuit at any given point. Buffer units can be added in parallel to increase

the output ampacity or the hold-up time.

The YR2.DIODE is a dual redundancy module, which has two diodes

as decoupling devices included. It

can be used for various purposes.

The most popular application is to

configure highly reliable and true

redundant power supply systems.

Another interesting application is

the separation of sensitive loads

from non-sensitive loads. This

avoids the distortion of the power

quality for the sensitive loads

which can cause controller fail
