The Ashly RPS-18 Inline Power Booster is a 100-240V, 50-60Hz AC adapter providing 24VDC and 625mA maximum current. It uses euroblock terminals on both ends for easy insertion between the host unit's Remote Data Port and WR-5 Input jack. Alternatively, it can be inserted between the J3-LINK jack of any of the first four WR-5 remotes and the J2-INPUT jack of the next WR-5 in the chain. This latter application can be useful to overcome voltage losses, caused by long cable runs to multiple remotes.
