Fact Sheet

NEMA 3R Rated VLT® AQUA Drive

The VLT® AQUA Drive withstands outdoor
environments. A NEMA/UL Type 3R rated enclosure,
and standard 1,000-foot motor cable runs, provide
maximum mounting exibility.

Power range:

1-phase, 200–240 VAC: 1.5–30 HP



1-phase, 380–480 VAC: 10–50 HP



3-phase, 200–240 VAC: 1/3–60 HP



3-phase, 380–480 VAC: 1/2–450 HP



3-phase, 525–690 VAC: 15–400 HP



Suitable for installations that require
protection against rain or splashing water,
NEMA/UL Type 3R rated variable frequency
drives can be installed directly at the
equipment location without an additional
protective enclosure. The variable frequency
drive is built with all cast aluminum parts so
that the enclosure will not rust.

Feature Benet

SmartStart programming Quick and easy start-up

All cast aluminium parts No need for separate cover or enclosure*

Conformal coated circuit board option Additional protection in corrosive environments

Info key opens on board manual No manual needed to operate

Initial Ramp Performance that matches pump demands

Fan designed to withstand moisture and rain Reliable operation

Flow compensation Improved setpoint control

End of pump curve detection Protects pump, detects leakag

No/low flow detection Pump protection

Pipe fill mode Eliminates water hammer

Can be installed near the motor or blower Facilitates modular plant design

1000’ motor cable runs (unshielded) Short motor cables reduce EMI/RFI

Phase Conversion

For remote areas such as lift stations or
farming fields where 3-phase power is not
available, single-phase drives offer phase
conversion and speed control in a single,
compact package. Phase-converting VLT®
AQUA Drives enable the use of cost-effective
three-phase motors with only single-phase,
240 VAC or 480 VAC service.

Perfect

tool for: lift stations,
pump stations, golf
courses, irrigation,
and other outdoor
applications

Reliable Maximum uptime

Robust, single enclosure Reduced cost and maintenance

Unique cooling concept with no ambient air flow
through electronics housing

Max. ambient temp. 50° C without derating No external cooling or oversizing necessary

User friendly Simplied operation and lower costs

Award-winning LCP keypad design

Easy installation Lower startup costs
Watertight USB plug can be mounted in the bottom

of the drive

* For outdoor installations: The drive must be installed under a suitable cover with weather shield to protect from direct
exposure to sun, snow and ice.

Reliable operation in harsh environments

Reduced space requirements and commissioning
time

Drive enclosure can remain closed while making
setup or programming changes
