KV4800
KEMRON KV4800 Variable Frequency Drive
BOM & application review — reply in 1 business day
The Kemron KV4800 is an economy high-performance VFD (0.4–15 kW three-phase / 0.4–2.2 kW single-phase) with sensorless-vector and V/F control, PMSM and induction support and Modbus RS-485, supplied by Automation Liberty as a candidate for Mitsubishi FR-E700-class applications. Motor data, control mode and protocol are validated in an engineering review before quoting — a candidate, not a catalog swap.

Engineering notes
For the KV4800, engineering review covers motor nameplate data, supply and load conditions, duty, control mode, braking, terminal functions, and the required communication protocol. Any cross-brand proposal is a candidate replacement — subject to engineering review.
- Economy-class drive: 3-phase to 15 kW, 1-phase to 2.2 kW, SVC and V/F only — not a closed-loop or heavy-hoist candidate
- Mitsubishi Pr.-parameters and FR Configurator files do not transfer — commissioning restarts from zero on the KV4800 group-code scheme
- Modbus RTU only, factory default 9600 bps 8N2 — note the 8N2 framing
- CC-Link or option-card ecosystems have no equivalent here
- On 220 V supply, wire L1 and L3 only (L2 stays open) — a known installer trap
Frequently asked
What applications is KV4800 intended for?
The product record describes KV4800 for constant-pressure water supply, fans and blowers, woodworking machinery, logistics and conveyors, food packaging, CNC machine tools, and medical or dental engraving equipment.
