Xylem IM255 AQUAVAR Intelligent Pump Controller - Manual (Page 130)

• LCP and typical control card power consumptions are included. Further options and
customer load may add up to 30 W to the losses. (Though typically only 4 W extra for
a fully loaded control card or options for slot A or slot B, each)
• Although measurements are made with state of the art equipment, some
measurement inaccuracy must be allowed for (±5%).
6) A2+A3 may be converted to IP21 using a conversion kit. (See Pricebook for conversion
kit order numbers.)
7) B3+B4 and C3+C4 may be converted to IP21 using a conversion kit. (See Pricebook for
conversion kit order numbers.)
General technical data
Mains supply
Supply terminals L1, L2, L3
Supply voltage 200–240 V ±10%
Supply voltage 380–480 V/525–600 V ±10%
Supply voltage 525–690 V ±10%
Mains voltage low/mains drop-out: During low mains voltage or a mains drop-out, the
drive continues until the intermediate circuit voltage drops below the minimum stop level,
which corresponds typically to 15% below the frequency converter’s lowest rated supply
voltage. Power-up and full torque cannot be expected at mains voltage lower than 10%
below the frequency converter’s lowest rated supply voltage.
Supply frequency 50/60 Hz ±5%
Maximum imbalance temporary between mains phases 3.0% of rated supply voltage
True power factor (λ)
≥ 0.9 nominal rated load
Displacement Power Factor (cos φ) near unity (> 0.98)
Switching on input supply L1, L2, L3 (power-ups) ≥ 10
HP
maximum 2 times/minute
Switching on input supply L1, L2, L3 (power-ups) 15-100
HP
maximum 1 time/minute
