⚡️LS Electric H100+ VFD: A Smarter, Stronger Solution for Fan & Pump Control
When it comes to HVAC, water treatment, and pump‑driven systems, reliability and efficiency aren’t optional — they’re essential. LS Electric’s H100+ Fan & Pump Drive is engineered specifically for these demanding environments, delivering intelligent control, robust protection features, and modern communication options that make integration seamless.
Let’s breakdown what makes the H100+ a standout choice for OEMs, contractors, and facility engineers.
💨Purpose‑Built for Fan & Pump Applications
The H100+ isn’t a general‑purpose VFD — it’s optimized for the real‑world challenges of HVAC and pumping systems.
Key Application Features
Soft Fill Operation Prevents pump damage from sudden pressure changes during startup.
Start/End Ramp Control Smooth acceleration and deceleration to protect piping and pump components.
Deceleration Valve Ramp Reduces pressure shock when stopping or closing valves.
Multi‑Motor Control (MMC) One drive can control 1 main motor + up to 5 auxiliary motors, ideal for multi‑pump systems.
Lead‑Lag Pump Control Automatically rotates pump duty cycles to extend equipment life.
No‑Flow Detection & Over‑Cycle Protection Helps prevent dry‑run conditions and system inefficiencies.
Fire Mode Ensures continuous operation during emergency conditions.
⚙️Built‑In Convenience & Smarter Operation
The H100+ is designed to make installation, commissioning, and maintenance easier.
User‑Focused Design
HVAC‑exclusive keypad with HAND/AUTO modes
Easy‑change cooling fan without opening the drive cover
Smart Copier for fast parameter upload/download
Side‑by‑side mounting for space‑efficient panel layouts (up to certain kW ranges)
🔗Modern Communication & Integration
The H100+ supports the protocols used across building automation and industrial control systems.
Standard Built‑In Protocols
Modbus‑RTU
Metasys N2
BACnet MS/TP
Optional Communication Cards
