Economical and reliable supply even in extreme conditions:
single-phase PROtop versions with innovative DCL
technology for permanently reliable operation – even at
–40°C
The benets of DCL technology
• Reliable triggering of circuit breakers
• Dynamic and powerful motor starts
• Additional power reserves
High-end power supplies need to perform efciently and reliably even in
challenging industrial environments. This requires high power reserves, a long
service life and optimal protection against surge voltage, vibration and extreme
temperatures.
PROtop power supplies have a particularly robust network input level and are
not sensitive to mechanical inuences. This guarantees reliable operation even in
challenging conditions such as those in wind power installations.
Thanks to the future-oriented DCL (dynamic current limiting) technology, high
pulse reserves are available at all times. The resulting dynamic range can be used
for the reliable triggering of circuit breakers or for powerful motor starts. At a
motor’s starting torque, for example, approx. 300% power reserve will be available
for approx. 100 ms, and 150% for approx. 5 s. For reliable tripping of line circuit
breakers, even 600% is available for 15 ms.
Outstanding peak load reserves thanks to DCL technology
PROtop meets the highest demands

The distance between the Power Supply and the load (l) is
measured under real conditions.
The following parameters are the basis of measurement:
• Siemens circuit-breaker (5SY61xx-x)
• The short circuit generated by a semiconductor switch
• In addition to the short circuit current, the Power
Supply provides half of the nominal current for a parallel
connected load
