DC Back-Up Solutions: UPS and Buffer Modules

PULS DC-UPS and buffer modules increase system reliability and prevent unplanned and expensive downtimes, loss of data, and long restart sequences

Image of PULS' DC-UPS and Buffer Modules

PULS’ DC-UPS and buffer modules are efficient, compact, and reliable to ensure high system availability, and are available with capacitor storage or VRLA batteries.

DC-UPS with Battery Storage

DC-UPS systems require three elements - a power supply, a DC-UPS, and a battery - to provide back-up power. The DC-UPS controllers are responsible for monitoring and charging the battery as well as controlling the seamless transition between normal and buffer mode. They bridge power failures or voltage fluctuations for seconds, minutes, or even hours, depending on the back-up load requirements, and increase system availability.

Benefits
  • One-battery-concept: each battery is individually charged and monitored, avoiding the need for matched batteries
  • Optimized battery management system for the longest battery life
  • Easy and self-explanatory plug-and-play
  • Temperature compensation for accurate end of charge voltage adjustments
  • Adjustable maximum buffer time to maximize battery lifetime

DC-UPS with Capacitor Storage

The DC-UPS with integrated electrochemical double layer capacitors, often called ultra-caps or super-caps, are service-free and guarantee an uninterrupted power supply for periods measured in seconds to minutes.

Benefits
  • No service needed for entire lifespan: battery-free backup solution
  • Stabilized output voltage in buffer mode
  • Wide operational temperature range fully rated from -40°C to +60°C
  • Output decoupled from input allows for buffered and unbuffered branches
  • PC mode feature
  • Protected against overload and short-circuit

Buffer Modules with Capacitor Storage

Buffer modules with electrolytic capacitors work similarly to a DC-UPS and can bridge power failures for periods measured in milliseconds to seconds.

Benefits
  • Service-free for entire lifespan
  • Stabilized output voltage in buffer module
  • Wide operational temperature range fully rated from -25°C to +70°C
  • 24 VDC and 48 VDC output voltages
  • Parallel capable for increased buffer time or increased buffer current
  • Selectable backup behavior
  • Protected against overload and short-circuit
