PC7 Specifications Mini Vector AC Drive The PC7 is our newest “Power Cube” inverter. It offers both PC7 sensorless vector and V/Hz control modes. The small Mini Vector AC Drive footprint, RS-485 port, and programmable I/O make this product ideal for new and retrofit applications. The package is NEMA 1 as standard, but high volume OEM’s can also Ratings: order chassis, flat-panel heatsink or units without speed pot. 0.13 to 10 HP at 230 Vac 0.50 to 10 HP at 460 Vac Approvals: Performance: Sensorless Vector: 0 0 • UL, cUL, CE (73 / 23 / EEC) • Adjustable accel/decel: • Speed regulation: (15 to 35 C) 0.1 to 6000 sec 0.2% with digital reference • Speed resolution: • Braking torque: Design: Average decel torque: Digital 0.01 Hz to 100 Hz • Analog monitor output (programmable) 0.1 Hz above 100 Hz 50% to 2 HP • Auto tune to motor characteristics 30% 3-10 HP Analog 1/1000 or Fmax • Energy saving control • 150% starting torque @ 1 Hz Cont. regen torque: • Form A output relay (programmable) 20% - no DB Resistor • MTBF: exceeds 83 years 150% - DB Resistor V/Hz Mode: • NEMA 1 enclosure (chassis by (transistor built-in) 0 0 removing conduit box) • Speed regulation: (15 to 35 C) • Controlled speed range 0.5 to 1% with slip compensation • Overload capacity: 150% / 1 min. 40:1 Volts/Hertz • Peak current rating: 250% • Speed resolution: 100:1 Sensorless vector Digital 0.01 Hz to 100 Hz • Pulse train input reference capability • Displacement power factor: 0.98 0.1 Hz above 100 Hz • Quick start keypad with speed • Drive efficiency: 96 to 98% Analog 1/1000 or Fmax potentiometer • Output frequency: 0.1 to 400 Hz • 150% starting torque @ 3 Hz • RS-485 port (Modbus) on terminal strip • Set point PID control Protection: • Up to 10 kHz carrier for low noise • DC bus CHARGE indicator • 2 open-collector outputs • Electronic motor overload (UL approved) (programmable) • Fault circuit: overcurrent, inverter • 7 programmable digital inputs • 16 preset speeds overload, overvoltage, undervoltage, overtemperature and fan fault. • Ground fault protection Operating Conditions: • Optically isolated inputs • Altitude: to 3280 ft (1000 m); higher by • Phase-to-phase / phase-to-neutral short derating circuit protection • Ambient service temperature: • Stall prevention to prevent nuisance trips 0 0 0 -10 C to 50 C (122 F) Chassis 0 0 0 -10 C to 40 C (104 F) NEMA 1 • Ambient storage temperature: 0 0 0 0 -20 to 60 C (-4 to 140 F) • Humidity: to 95% non-condensing • Input voltage: +10% / -15% 200 to 230 Vac, 3-Phase 380 to 460 Vac, 3-Phase • Single-phase input with 30% derate • Service factor: 1.0 Options: • DIN rail kit • DB resistors • Flat heatsink design • Open chassis design • Rapidpak (future) • Remote operator (JVOP-146) • Saflink • NEMA-4 Prices and specifications subject to change without notice. 5580 Enterprise Parkway Fort Myers, FL 33905 Effective Date: August 15, 2000 Phone: (941) 693-7200 Discount Symbol: DPD1 59 Fax: (941) 693-2431 ©2000 Saftronics Revision 1.1 PC7
