Approvals

WARNING: Cancer and Reproductive Harm California Proposition 65

Several pieces of equipment can share the same source of regulated power with the Sola MCR Series power regulators. This is ideal for surges, dips, brownouts, and drop-out situations. These power regulators offer automatic overload protection. For customizing your connection needs, the MCR regulators are available in a variety of VA output sizes.
