Through experience, we have determined the real-world requirements for reliable power systems in extremely harsh environments and have designed our Variable Speed Drives and Electrical Distribution Systems to exceed these operating parameters.
- Electrical Submersible Pumps (ESPs)
- Progressive Cavity Pumps (PCPs)
- Sucker Rod Pumps (SRPs)
- Industrial Horizontal Pump Systems (HPS)
- Industrial Motor Drives for pumps, fans, and similar applications
EnerDrive AC drive HMI control systems use touch screens for low-temperature applications and LCD keypad for high-temperature applications. Our HMIs are intuitive and include all of the protective features normally associated with pump type applications such as;
- Load related under and over current
- Under and over voltage
- External analog and external digital controls
- Reverse rotation
- True fundamental output voltage
- Frequency and current leakage monitoring (optional)
Advanced features of EnerDrive VFD AC Drives’ include:
Meets IEEE Harmonics Standards
EnerDrive VFD systems configured with 12, 18, or 24 pulse front-end rectifiers are pre-configured at the factory to meet the final application design requirements. Load test may be performed on request to pre-determine performance.
VFD Enclosure Construction
Direct On Line (DOL) Bypass Feature
The EnerDrive DOL VFD bypass system is used when a fully redundant power system is required. The VFD bypass system contains switches and contactors that are engaged by a manual or motorized external selector switch. This allows motor power to selectively come from the Variable Frequency Drive or an across-the-line starter, reducing lost operating time.
Output Waveform Sinewave Filter (Optional)
EnerDrive AC drive systems may be specified with the EnerWave IEEE 519 standard compliant line, sinewave, or dv/dt filters. The ED-600 Series Sinewave Filter dissipates the high-frequency harmonics on the VFD output, so that the output then resembles a true sinewave. RESULT: lower insulation stress and longer motor-cable system run-life.
Transient Voltage Surge Suppressors (TVSS) (Optional)
A TVSS uses state-of-the-art MOV devices assembled in a non-destructive, fuse-protected NEMA 4 enclosure. The device may be mounted inside the Variable Speed Drive electrical enclosure without additional protective devices such as circuit breakers.
