PL4150-150kW-Programmable-Load-Box

150 kW Programmable EVSE Load Bank (PL4150)

150 kW Programmable EVSE Load Bank (PL4150)

The TESCO PL4150 provides adjustable, programmable AC and DC load simulation for testing electric vehicle chargers up to 150 kW. It creates repeatable load profiles that mirror real EV charging behavior, making it ideal for EVSE commissioning, performance verification, and metering accuracy testing. When paired with the TESCO T4350 or T4000 EVSE Test System, it becomes a complete solution for validating charger output and communication.

Description

Simulate Real-World EV Charging Load Up to 150 kW

The PL4150 applies controlled AC or DC load to electric vehicle chargers to evaluate output behavior, stability, and performance. Load profiles can be adjusted to match the current-draw patterns seen during real EV charging sessions.

Charger-Agnostic Design for AC and DC EVSE

The PL4150 is compatible with any EV charger supported by the T4350, including:

  • CCS1
  • CCS2
  • NACS
  • CHAdeMO
  • GBT

This allows one load bank to be used across multiple charger types and charging networks.

Built for Utilities, OEMs, and EVSE Field Technicians

The PL4150 is designed for organizations that need accurate, repeatable load testing:

  • Electric utilities
  • Charger manufacturers and OEMs
  • Engineering labs
  • Commissioning teams
  • Troubleshooting and maintenance contractors

Its NEMA 3R enclosure, safety sensors, and rugged construction make it suitable for both field and lab environments.

Pair with the T4350 for Complete EVSE Testing

When combined with the TESCO T4350 EVSE Test System, the PL4150 enables:

  • Load performance verification
  • Charger communication and signaling checks
  • Output analysis under controlled load
  • Metering accuracy evaluation
  • Validation of AC and DC charging behavior

PL4150 Features and Capabilities

  • Programmable Load Simulation: Apply adjustable AC and DC load profiles to evaluate charger behavior under different operating conditions.
  • Environmental & Safety Monitoring: Built-in sensors measure temperature, humidity, and fan speed during operation. Safety sensors protect the unit during high-power cycles.
  • NEMA 3R Outdoor-Rated Enclosure: Suitable for field deployment, with robust construction and weather resistance.
  • Automatic Cool-Down System: Ensures safe shutdown and protects internal components after load testing.

Field Deployment & Installation

The PL4150 is large, heavy, and contains moving parts. It requires a forklift or crane for safe installation. Forklift channels and lifting eyebolts are included for proper handling and placement during field or lab operations.
