What Applied Energy does

Applied Energy LLC is a privately held US manufacturer of power quality protection hardware, founded in 2002 by Dan Princinsky (President) and Bill Hinton (Director of Engineering) and headquartered in Saginaw, Michigan. Its core offering is the Phaseback Voltage Stabilizing Ground Reference (VSGR), a patented (US Patent 10,985,648 B2) device that corrects phase voltage imbalance, suppresses surges and harmonic noise, prevents arcing ground faults and arc flash events, and protects power systems up to 230KV. The portfolio has been extended with the Harmonic Silencer, the Phaseback DC Choke, and the Drive Voltage Stabilizer (DVS), each addressing adjacent power-quality failure modes across AC and DC circuits.

The underlying technology differentiates by controlling voltage (using thousandths of an amp) rather than dissipating current surges (using hundreds to thousands of amps via traditional MOV/TVSS devices), operating at the speed of current flow and producing measured outcomes of 85%+ arc flash reduction, 85% harmonic reduction, and payback typically within one year. Independent KEMA Laboratories validation (2017), a documented 15+ year fault-free operating track record, and a lifetime warranty underpin the technical claims. The product family is sold through a territory-based network of independent sales representatives across roughly a dozen US states, with each unit custom-sized to the buyer's transformer capacity (kVA and voltage). Pricing is quote-based and not publicly disclosed; the company offers a 30-day money-back guarantee in the US.

Customer evidence spans industrial manufacturing, automotive complexes, wastewater treatment, maritime/offshore vessels, education, agriculture, government/military (US Coast Guard), and emerging positioning in utilities for EMP and geomagnetic-storm mitigation. All revenue is derived from hardware sales of these custom-configured units; no software, recurring service, or licensing components are present in the data, and the company is bootstrapped with no disclosed external funding, acquisitions, subsidiaries, or restructuring activity.

Revenue model

1. Phaseback VSGR Hardware Sales: Sale of the core Phaseback VSGR unit, sized and built to protect all electrical loads powered from the power transformer. Products are sized based on transformer capacity in kVA and secondary voltage. Covers power systems from 5 volts DC through 230,000 volts AC.
2. Harmonic Silencer Sales: Sale of harmonic filter products for WYE power systems, sold in conjunction with or independent of VSGR units.
3. Phaseback DC Choke Sales: Sale of DC choke products for industrial VFDs, UPS systems, DC crane drives, electric vehicle applications, and battery chargers.
4. Energy Savings/ROI: The company markets that products typically achieve payback/ROI of less than 1 year through energy savings, reduced equipment failures, and prevented downtime.

Core offering

Applied Energy designs, manufactures, and sells proprietary power quality protection devices under the Phaseback brand. Its flagship offering, the VSGR (Voltage Stabilizing Ground Reference) system, is a patented hardware unit that stabilizes phase voltages, eliminates harmonic noise, prevents ground faults and arc flash, arrests lightning, and mitigates EMP events in 3-phase power systems from 5V DC through 230,000V AC. The product is custom-sized to customer transformer capacity (kVA and secondary voltage) and is sold with a lifetime warranty and 30-day money-back guarantee.

Product overview

Applied Energy offers a suite of power quality protection devices built around the Phaseback VSGR core technology. The main product line includes the Phaseback VSGR (Voltage Stabilizing Ground Reference) as the core patented system, supplemented by the Harmonic Silencer (parallel-connected harmonic filter for WYE systems), and the Phaseback DC Choke (full-range harmonic filter for DC circuits). The Drive Voltage Stabilizer is a sub-product/feature that extends motor protection capabilities. These products work together to provide comprehensive power quality management including voltage stabilization, harmonic reduction, arc flash prevention, and energy savings, with typical payback within one year.

Products and services

• Phaseback VSGR (Voltage Stabilizing Ground Reference) Patented, custom-sized hardware unit that provides real-time voltage balancing and power quality control in 3-phase power systems up to 230KV. Prevents arc flash, eliminates harmonic noise, arrests lightning, mitigates EMP, prevents ground faults, corrects phase imbalance, and operates at the speed of current flow (186,000 miles per second) using voltage control rather than current control. Sized to customer transformer capacity (kVA and secondary voltage).
• Harmonic Silencer Parallel-connected power filter for WYE power systems that reduces and cancels harmonics and transient voltage spikes. Self-protected with a positive temperature coefficient system, reacts instantaneously (limited only by inductive charging rate), reduces harmonics/transients by 200–400%, can extend motor life by allowing a ~10°C reduction in heat energy, and can be installed in parallel with loads without equipment shutdown.
• Phaseback DC Choke Full-range harmonic filter for DC circuits that removes AC noise at all frequencies through 296,829 Hz. Uses mutual counter-electromagnetic inductance to suppress harmonic noise by combining properties of series and parallel opposing magnetic forces, rather than dispersing noise as heat. Sold for use with industrial VFDs, UPS systems, DC crane drives, electric vehicle applications, and battery chargers.
