FAQ
1
Does the 10kW load step meet my application requirements?
The 10kW step fully satisfies demands in most scenarios:
- Generator testing: Enables full load tests at 0%, 10%, 20% ... 100%
- UPS system: Supports standard load tests of 25%, 50%, 75% and 100%
- Transformer testing: Conduct full-load temperature rise tests and load characteristic tests
Only applications requiring ultra-precise load adjustment (e.g. laboratory research) need the 1kW-step SILV-1000L. The 10kW step is sufficient for industrial use.

Can SILV-1000LT operate at 380V?
Yes, with power derating:
(1) 1000kW at 400V
(2) 900kW at 380V (10% power derating)
Power is proportional to the square of voltage. If your power supply is 380V, SILV-1000LT is recommended, which can still deliver 900kW to meet most application needs.

How does the heat dissipation system of SILV-1000LT work?
It adopts forced air cooling with top air outlet, heat dissipation capacity: 50m³/kW/h
1. Heat is generated by resistors and monitored by built-in temperature sensors
2. Fans start automatically once temperature reaches the preset value
3. Vertical airflow discharges internal heat efficiently
4. Fans stop or run at reduced speed as temperature drops
This design ensures stable operation even under ambient temperature up to +50℃, supporting 24-hour continuous full-load operation.

What safety protections does SILV-1000LT have?
It is equipped with multiple safety protection functions:
1. Main circuit breaker protection: Schneider EVS 2000A main breaker for automatic power cut under overcurrent
2. Isolator protection: HGL 1600/3P isolator to guarantee electrical safety
3. Thermal protection: Automatic power-off against overheating
4. Airflow protection: Power cut upon fan failure to avoid overheating
5. Fan overload protection: Prevent fan burnout
6. Emergency stop: One-click emergency power-off to ensure personnel safety

7
How to perform regular calibration on SILV-1000LT?
Calibration steps:
1. Measure actual output power via high-precision power analyzer
2. Compare measured data with set values and calculate deviation
3. Adjust resistors or control system if deviation exceeds ±3%
4. Full calibration is recommended once a year11.
