What is 'RPM' (Rational Power Management)

Lab.gruppen’s D Series provides consultants and integrators with unprecedented flexibility for specifying amplifier output channels to meet the varying load conditions within a single complex project. For the first time, Rational Power Management (RPM™) provides true flexibility in allocating available power across the four output channels. 

Each channel may be tailored to meet the requirements of the connected load, and any power not used for that channel may be allocated for use on other channels.  In addition, regardless of model, RPM’s LOAD-MAX feature ensures that one or more channels can supply up to 5000 W of output (1 channel on D 80:4, two on D 120:4, all four on D 200:4). This avoids amplifier “over-specification” on all channels (inefficient use of total amplifier inventory) or bridging of adjacent channels (thus reducing channel count) in order to meet minimum demands on one power-hungry load. 

RPM also incorporates LOAD-GUARD, a unique feature that safeguards the defined power output of one or more specified channels. Defined in the CAFE software, LOAD-GUARD assures that the full output power will be maintained regardless of demand of on other channels, with the remaining channels responding to a best-case scenario to deliver defined power output while maintaining rail voltage and power supply optimisation. 

Rational Power Management results in real-world savings, both immediate and long-term. In many cases, fewer amplifiers – or lower cost models – may be specified while still fulfilling all power requirements. It also allows better mains management, avoiding over-specification of costly infrastructure components including mains distribution, cooling, and UPS (where required, such as mission-critical Voice Alarm/Emergency Evac systems). Finally, the overall gains in efficiency in larger systems will minimize current consumption and reduce operation costs – a “green bonus” for the system owner.
