Highlights
- Four devices, one power supplyFour DC outputs run from a single supply through one XT60 input, so the row of separate adapters under the tank collapses into one unit. Each port is switched independently rather than sharing a single on/off.
- Output follows input, 11–26 VThe controller passes the input voltage straight through instead of converting it, accepting anything from 11 to 26 V DC. You match one supply to your equipment and everything downstream sees exactly that voltage.
- Two current ceilings, chosen by what you runThe Gen 1 Standard handles 10 A and 240 W at 24 V for lights, fans and solenoid valves. The Gen 2 Pro goes to 12 A and 288 W, which is what pumps require — return, top-off, drain and wave — with headroom left for startup surge.
- Scheduled and remote, with manual override2.4 GHz Wi-Fi and the YuzhaLink app cover remote switching, timed automation and OTA firmware updates. A physical switch keeps master and per-channel control available when the network is not, and power-loss memory restores channel states after an outage.
- Protection you can actually seeOver-current, over-voltage and short-circuit protection sit behind all four ports, and current monitoring reports what each channel is drawing — so an equipment fault shows up as a reading rather than as a mystery.
- Built for the cabinet, not the sumpFlame-retardant ABS at 110 × 50 × 21.5 mm and 79 g, running at ≥95% efficiency from -10 to 50 ℃, mounting on two supplied M4 screws. The IP20 rating makes it strictly a dry-location device.

About this product
This 4-channel low-voltage DC power controller is designed for aquarium ecosystems, supporting independent multi-channel control and automatic scheduling, removing the clutter of multiple adapters and keeping the aquarium cabinet tidy.
Centralised power for aquarium equipment: 4 universal DC ports (5.5×2.1 mm), up to 3A per channel, with a total current ceiling that varies by generation (Gen 1 Standard 10A, Gen 2 Pro 12A). Both generations can be used with fans, solenoid valves, low-voltage lights and other low-voltage DC equipment; both also cover automatic top-off and drain where a solenoid valve does the work. Water pumps, top-off pumps, drain pumps and wave pumps are supported on the Gen 2 Pro only, and must stay within the 3A per-channel limit and the unit's total current ceiling while leaving headroom for startup current. A power supply is not included — you supply a DC source that meets the voltage and power requirements. Wide voltage compatibility: 11–26V DC input, with the output voltage following the input, for safe and stable operation. Multiple safety protections: built-in over-current, over-voltage and short-circuit protection, with current sensing. Smart control: a built-in Wi-Fi module allows remote control and scheduling through the YuzhaLink APP, with power-loss memory and OTA firmware updates. Design and materials: flame-retardant ABS. Installation constraints: IP20 rated, suitable for dry locations only; avoid drips, condensation, salt spray and direct splashing.
