Tight line-load regulation ensures that the output voltage holds steady from no load to full load. This keeps pumps, motors, and lights working at the correct voltage even during brown out situations. Proportional Fan Circuitry provides an extra measure of protection. During times of heavy load demands, the automatic circuitry will activate the fan before thermal stress can occur on any internal components. Reliability and durability is built into all DLS models.
External fuses can be quickly and easily replaced .
