The Reliance Electric SP500 1 HP 1SU21001 VFD Motor Speed Drive is an AC PWM (pulse-width-modulated) inverter that operates on single- or three-phase power. AC input power is applied to the drive’s input terminals. Voltage transients are suppressed by three metal-oxide-varistor (MOV) suppressors. These suppressors keep any input voltage transients within the maximum voltage rating of the input diode module.

 

Features:

  • On-board keypad and display
  • 500 millisecond power dip ride-through
  • 150% overload for one minute (nominal)
  • 0.5 to 240 Hz three-phase voltage output
  • NEMA 1 and NEMA 4/12 enclosures
  • A snubber resistor braking signal and a scaled voltage analog output (0 to 10 VDC) which is proportional to: output frequency, output amps, output voltage, selected reference
  • Quiet motor operation with high carrier frequency selection
  • Drive protection: overcurrent, short circuit, ground fault, overvoltage, undervoltage, overtemperature
  • User-selectable relay contact for indications of drive running, drive faulted, or drive at selected speed
  • User-selectable power-up start, auto-restart, and coast-to-rest or ramp-to-rest stop functions
  • User-selectable local or remote operation
  • 29 user-adjustable software parameters

 

Specifications:

  • AC Line Distribution Capacity (Maximum): 100KVA, single-phase 115VAC and three-phase 230VAC, with 5,000 amps symmetrical fault current capacity
  • Control Method: All-digital, pulse-width-modulated (PWM)
  • Carrier Frequency: 4 kHz, 6 kHz, or 8 kHz, software selectable
  • Displacement Power Factor: 0.96
  • Line Frequency: 50/60 Hz (± 5 Hz)
  • Line Voltage Variation: –10% to +10%
  • Line Dip RideThrough: 500 milliseconds
  • Linearity: 0.05 (Speed reference to output frequency)
  • Long-term Frequency Stability: 0.01%
  • Minimum Frequency Range: 0.5 – 30 Hz
  • Maximum Frequency Range: 30 – 240 Hz
  • Maximum Load: 150% for 1 minute (nominal, based on drive nameplate rating)
  • Motor Lead Lengths: 76 meters (250feet) total (See table 3.7 for more information)
  • Overcurrent Trip IET: 200% rated drive current
  • Analog Speed: Reference 0 to 10 VDC or 0 to 20 mA
  • Start: Edge-sensitive signal that must see an open-to-closed contact transition. This transition may be a momentary or fixed closure.
  • Stop: An open contact that must be closed when the drive is running. The drive will remain off as long as the contact is open.
  • IET Reset: Edge-sensitive signal that must see an open-to-closed contact transition. This transition may be a momentary or fixed closure.
  • Forward/Reverse: An open contact to assert the forward direction and a closed contact to assert the reverse direction.
  • Function Loss: An open contact that must be closed when the drive is running. When the contact is open, the drive turns off. The drive will remain off as long as the contact is open.
  • Analog Output (0-10 VDC scaled signal):
    • Output Voltage: 0 to 253 VAC
    • % Load (Amps): 0 to 200% (Percentage of output amps based on the drive nameplate.)
    • % Selected Speed Reference: 0 to 100% (Percentage of the selected reference signal range.)
  • Snubber Resistor Braking: Snubber resistor control signal used by an optional snubber resistor.
  • Output Status Relay: 115 VAC/24 VDC, 0.5 Amp, relay output (One Form A and one Form B contact wired with a single common.)
  • Input Power and Horsepower Rating: Three-Phase - 1 HP
  • NEMA Rating: 1
  • Enclosure Size: A
  • AC Input Volts: 200-230
  • Input Amps: 7.0
  • Input KVA: 2.8
  • Output Amps: 5.0
  • Power Loss Watts: 70
  • Enclosure Type: A 
  • Dimensions: 5.75” W x 12” H x 4.8” D (14.6 cm x 30.48 cm x 12.19 cm) 
  • Weight: 6 lbs (2.7kg)
