Overview
The 5KW is an Automatic Voltage Regulator (AVR) that maintains the generator output voltage within precise limits by controlling the exciter field current. It continuously samples the generator output voltage and adjusts excitation to compensate for load changes, engine speed variations, and temperature drift.
Key Features
- 5KW Rated — For medium gasoline generators
- 120V/240V Selectable — Global voltage compatibility
- 5A Continuous Output — 63VDC max for reliable excitation
- Solid-State Design — No moving parts, long service life
- Self-Excited Shunt — Proven reliable topology

| Frequency | 50/60Hz auto | 50/60Hz auto |
| Generator Compatibility | Universal (most 5kW gasoline) | Kipor KDE series only |
| Build Quality | Basic | OEM-spec |
| Price | $8-15 | $12-22 |
Selection Advice
The key decision factor is the generator brand. For non-Kipor generators, the 5KW Universal model is the correct choice — it provides broader compatibility at a lower price, and the ±2% regulation is adequate for portable generators powering basic loads (lights, power tools, small appliances). The higher 5A output also provides more margin for generators whose field windings may have aged.
For Kipor generators specifically, the DAVR-95S is required. Kipor uses a proprietary AVR mounting bracket and connector layout that universal AVRs cannot physically fit. The DAVR-95S is built to Kipor OEM specifications with precise ±1% regulation — critical because Kipor’s inverter-generator hybrids are more sensitive to voltage fluctuations than conventional generators.
Important: do NOT install a DAVR-95S on a non-Kipor generator — the fixed 220V sensing and proprietary connector will not match, potentially causing over-voltage or no-output conditions.
