Space Critical Power Solutions
The DST is a high density Rackmount Distribution Panel designed to accommodate virtually any 48 VDC, 24 VDC or 12 VDC power distribution requirement. Its flexibility makes it ideal for all telecom site power requirements, large and small.
These distribution panels accommodate up to 10 or 20 circuit breakers (depending on model) within a compact rack-mount housing, occupying only 2 RU of rack space. The circuit breakers feature a unique plug-in design which requires only front access for quick, easy installation during initial power system configuration, as well as future system expansion.
Model DST-20A (UL) features dual
isolated 10 circuit A and B buses, each rated at 450 amps, enabling redundant
power configuration or different voltages/ground references. A and B inputs can
also be paralleled, creating a single900 amp bus. Model DST-10 (UL) has a single
450 amp bus which accepts up to 10 breakers.
Input/output wiring is rear access via
bus bars that accept single or double hole lugs. Input/output buses are secured
to the load breaker sockets via solid nickel-plated copper bus material.
