⚡️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

  • BACnet/IP

  • EtherNet/IP

  • Modbus TCP

  • LonWorks

This makes the H100+ easy to drop into existing BAS networks or new installations.

🔒Reliability, Safety & Compliance

The H100+ is engineered for long‑term durability and global compliance.

Protection & Safety

  • SCCR 100kA rating

  • Built‑in DC reactor (improves power factor & reduces THD)

  • Built‑in EMC filter for noise reduction (varies by kW range)

  • UL Plenum Rated — suitable for air‑handling compartments

  • Seismic‑rated design (OSHPD)

Environmental Ratings

  • -10°C to 50°C operating range (HD)

  • Up to 4,000m altitude with derating

  • 95% RH non‑condensing humidity tolerance

🔌Power Range & Availability

The H100+ covers a wide range of horsepower classes across multiple voltages:

  • 200–240V: 1–125 HP

  • 380–480V: 1–800 HP

  • 525–600V: 7.5–125 HP

This makes it suitable for everything from small booster pumps to large industrial fan systems.

🌱Energy Efficiency Built In

LS Electric positions the H100+ as an energy‑saving drive, especially for water treatment and HVAC applications. Features like optimized motor control, ramping, and multi‑motor sequencing help reduce energy waste and extend equipment life.

⭐Final Takeaway

The LS Electric H100+ VFD delivers reliable, application‑focused performance for HVAC and pump systems, with smart control features, modern BAS communication options, and built‑in protection designed for long‑term durability. If you’re looking for a drive that’s easy to integrate, easy to operate, and engineered specifically for fan and pump applications, the H100+ is a strong fit for both new installations and retrofit projects.
