Discover YINTO's full range of resistive load banks — from compact suitcase units to high-power industrial systems.

$CATEGORYS[$catid][catname]}
Product Overview

YINTO resistive load banks are designed for testing AC power systems at unity power factor (PF=1). Ranging from 1kW to 1000kW with voltages from 110V to 690V, our resistive series provides precise, reliable load testing for generators, UPS systems, batteries, and power distribution equipment.

Built with corrosion-resistant alloy resistance elements and integrated high-efficiency cooling systems, every unit delivers consistent performance under continuous full-load operation — backed by comprehensive safety protections including over-temperature, over-current, over-voltage, and fan failure safeguards.

1.0 Power Factor — Maintains unity power factor during operation, with no reactive power. Ideal for accurate performance testing of generators, UPS and battery systems.
Highly Consistent Load Output — Provides highly consistent and linear load output, delivering precise, repeatable test results every time.
Pure Resistive Structure — Simple internal design without capacitive or inductive elements. It delivers high operational stability, easy maintenance and long service life.

Applications

Ideal Use Cases

Generator Commissioning

Full-load testing at 0.8 PF to verify generator performance, voltage regulation, and transient response under realistic operating conditions.

Factory Acceptance Testing

Comprehensive load testing for generator manufacturers to verify performance specifications before delivery to customers.

Data Center Infrastructure

Mission-critical testing of backup power systems including generators, UPS, and switchgear at realistic power factors.

Marine & Shipbuilding

Dockside and sea trial testing of shipboard power systems with combined resistive-inductive loads matching actual vessel demand.

Offshore & Oil & Gas

Rugged load testing solutions for offshore platforms, FPSO vessels, and remote energy facilities in harsh environments.

Renewable Energy Plants

Testing of solar inverters, wind turbines, and energy storage systems requiring realistic power factor simulation.

Key Features

Why Choose

Realistic PF 0.8 Testing

Simulates real-world inductive loads at 0.8 power factor — the standard rating for diesel generators and most industrial power systems.

Independent Load Control

Resistive and inductive sections operate independently, allowing PF=1 resistive-only testing, PF=0 inductive-only, or combined 0.8 PF operation.

High-Efficiency Cooling

High-speed axial cooling fans with integrated air duct structure ensure stable temperatures during continuous full-load operation.

Multi-Layer Protection

Over-temperature protection, over-current cut-off, over-voltage alarm, fan failure protection, and emergency stop button for maximum safety.

Premium Inductive Elements

High-quality air-core and iron-core inductors with stable performance, low noise, and long service life under continuous rated operation.

Smart Monitoring Software

PC-based monitoring and control software with real-time data display, data logging, test report generation, and remote load adjustment.
