3 Phase Resistive Load Bank Manufacturer Resistive Load Bank Wholesale - Rata
Product Overview
- Rata 3-phase resistive load bank, rated 15 kW (415/240 VAC), three-phase (21 A per phase), designed for continuous generator test operation.
- Compact, all-metal frame with powder coating, horizontal airflow, front control panel and handles; approx. 12–14" W x 18" L x 22" H, ~40 lb.
- Air-cooled integral fan, control circuit requires 110–120 VAC, 50/60 Hz.
Product Features
- Load configuration: 0 to +5% total load tolerance, load steps of 5 kW resolution (steps of 5 kW and 10 kW totaling 15 kW). Load connection via 8" pigtail power cable.
- Operator-friendly control panel with status indicators (airflow lights), main and independent load switches, fan on/off switch, and test sockets for instrument probes.
- Robust safety protections: fast branch fuses on all phases, fused control circuit, air pressure switch to prevent loading without cooling, overtemperature sensor to remove load, blower motor overload protection, and visible warnings on access panels.
Product Value
- Provides reliable, repeatable resistive loading for generator commissioning, testing, and maintenance—helping verify performance and prevent downtime.
- Compact and portable design makes it practical for field service, rental fleets, and in-plant testing where space and mobility matter.
- Strict quality control and skilled production ensure low defect rates and consistent performance, supporting long-term operational confidence.
Product Advantages
- Stringent quality management and thorough inspection at every production step for high reliability.
- Professional R&D and service teams and an established service system (pre‑sales, in‑sales, after‑sales) for customer support.
- Durable construction, stainless fasteners, easy handling, and multiple built-in safety features differentiate it from lower-grade alternatives.
- Designed for continuous duty with precise load stepping and stable cooling to protect both load bank and the device under test.
Application Scenarios
- Generator set commissioning, routine load testing and performance verification.
- Maintenance and capacity testing of UPS, switchgear, and backup power systems in data centers and industrial facilities.
- On-site service, rental companies, field testing for utilities, manufacturing plants, and educational or research laboratories that require controlled resistive loads.
