Aquacomputer PowerAdjust 3 USB, Ultra Version

The Aquacomputer Poweradjust 3 USB | Ultra Version (53167) is a single channel fan or pump controller for one 12 Volt DC device of up to 30 Watts, with USB, two aquabus connectors and aquasuite. It also works as an aquabus expansion device under an aquaero 5 or aquaero 6 unit.

Properties

• Channels: 1 power output for a fan or pump, DC 0 to 12 V, no PWM
• Output power: 30 W, 36 W with optional passive heat sink, peaks up to 54 W
• Connections: temperature sensor input, flow sensor input, speed signal output
• Interface: USB, two aquabus connectors
• Supply: 12 V from a PC power supply plug
• Size: 47 x 41 x 36 mm

Power for pumps and fans

Aquacomputer calls the poweradjust 3 versatile, mainly designed for Laing DDC and D5 pumps as well as powerful fans. It is capable of controlling a variety of devices with up to 30 Watts, or up to 36 Watts with the optional passive heat sink. One ultra version unit is enough, for example, for temperature dependent control of nine airstream fans on an airplex evo 1080 radiator.

To accommodate the high start-up currents caused by pumps and fans, short term peak loads may reach 54 Watts. A programmable start burst helps ensure pumps get enough power during start-up. Thanks to continuous speed signal checking, the start burst is triggered again (start burst repetition) upon a speed signal failure or when a missing flow signal is detected. The output is DC, no PWM, and runs at fixed power or fixed speed settings; the ultra version additionally offers temperature control.

What changed from the poweradjust 2

Compared to the poweradjust 2 predecessor, the connectivity options are the same: a power output with speed signal input, the USB interface for PC communication, temperature and flow sensor inputs and a speed signal output. The aquabus interface again connects it to an aquaero 5 or aquaero 6. The main new feature is a power output design in switching power supply technology, greatly improving efficiency and thereby reducing the waste heat of the unit.

Compatibility

Aquacomputer lists these devices for the aquabus, flow sensor and temperature sensor connectors:

• aquaero 6 XT (53146, 53206, 53250, 53251, 53262, 53263)
• aquaero 6 PRO (53145, 53253)
• aquaero 6 LT (53234)
• aquaero 5 XT (53089, 53125, 53249)
• aquaero 5 PRO (53090, 53252)
• aquaero 5 LT (53095)
• Flow sensor with 5.6 mm nozzle (53061, requires cable 53027)
• Flow sensor "high flow" (53068, requires cable 53027)
• Flow sensor high flow LT (53291)
• Flow sensor high flow 2 (53292)
• Temperature sensor inline G1/4 (53066)
• Temperature sensor inner/outer thread G1/4 (53067)
• Temperature sensor G1/4 (53147)
• Temperature sensor plug&cool (53025)
• Temperature sensor 70 cm (53026)

Notes

• The power output is not short-circuit proof, despite the over temperature protection.
• Without the heat sink the output carries 2.5 A (30 Watts); 3.0 A (36 Watts) needs the optional heat sink, which is not included.
• Turn off the power supply before connecting or disconnecting any cable.
