Schneider Electric AccuSine PCS+

• A complete solution for harmonic filtering that meets every harmonic standard around the world. Can be operated as a displacement power factor correction and load balancing device independent of or in conjunction with harmonic mitigation.

• Standard RMS output current ratings:

• 60 A, 120 A, 200 A, 300 A - 380 V AC to 480 V AC
• 47 A, 94 A, 157 A, 235 A - 480-600 V AC
• 40 A, 80 A, 133 A , 200 A - 600-690 V AC

• Nominal voltage:

• 380-480 V AC; +10%/-15%
• 480-600 V AC; +10%/-15%
• 600-690 V AC; +10%/-15%

• Up to 15kV with custom transformers

• Nominal frequency:

• 50/60 Hz, ±3 Hz auto sensing

• Number of phases:

• 3-phase, with or without neutral

• Spectrum cancellation:

• 2nd to 51st, discrete; fully selectable per harmonic order (amplitude and on/off)

• Harmonic Attenuation:

• Closed Loop: < 3 % THD(i); max 20:1 THD(i) reduction with load harmonic current above 50 % of AccuSine PCS+ rating
• Open Loop: < 5 % TDD
• Requires 3 % or higher inductive impedance per nonlinear load

• Power factor correction:

• Optimized unity PF, Leading (capacitive) or lagging (inductive) power factor (Cos φ) to target

• Mains current balancing:

• Negative sequence current injected to balance fundamental current on the mains due to load imbalance (inherently corrects displacement PF (Cos φ)

• Control response time:

• 25 μs

• Harmonic correction time:

• 2 cycles

• Reactive correction time:

• 1/4 cycle

• Operating Temperature:

• 60 A, 120 A & 200 A: IP00, IP20, UL Type Open, & UL Type 1 configurations -0 °C to 45 °C
• All others 0 °C to 40 °C
• Derate 2 % per degree °C to 50 °C

• Relative humidity:

• to 95 %, noncondensing

• Operating Altitude:

• 1000 m (derate 1 %/100 m above), max 4800 m

• Standards compliance/ certification:

• cULus (UL508 , CSA 22.2 No. 14)
• CE Certified, ABS, Lloyds, other local standards

• Display:

• 144 mm QVGA TFT 64k-color touchscreen

• Flexible and scalable:

 • All types of harmonic producing loads

• Single load, bus or global site filtering

• Compatible with future load changes

• Easy sizing and independent of system impedance

• Simple selection online tool

• Simple installation and ease of expansion

• Flexible parallel operation modes for multi-unit installations

• Current transformers can be installed on the incoming mains (source sense) or on the feeders to the loads (load sense) for maximum installation flexibility

•  Peace of mind:

•  Achieves compliance with any harmonic standard anywhere around the world when sized correctly

• Compatible with generator sources - off loads generators of reactive and harmonic current demands to extend life and ensure proper operation of generators

• Compatible with UPS sources: relieves UPS of reactive and harmonic current demands to ensure proper operation of UPS

• Ensures energy efficiency by optimising transformer and cable capacities; reduces utility power factor penalties; and saves the cost of generation and transmission of reactive and harmonic current (non active currents)

• Maximises up time when used for harmonic and/or power factor correction.

• Приложения:

• Anywhere nonlinear loads are present: water/wastewater facilities, HVAC systems, oil & gas platforms, petrochemical plants, port cranes, mining, pharmaceuticals, pulp & paper, automotive plants, all-electric ships, wind mill and solar farms, steel mills, plastic extrusion plants, and more.

• Stop voltage sags and flicker due to load current fluctuations (VAR compensation): Ball mills, shredders, arc welders, arc furnaces, hard to start AC motors, and more.
