Technical Insights
Why 1A Output Matters:
Enables testing of high-capacitance loads (e.g., long cables) without voltage collapse - critical for IEC 60840 compliance.
Weight Revolution:
Advanced core materials (amorphous steel?) reduce weight by 40% vs conventional 150kVA units.
Overload Engineering:
Special duct cooling in windings allows 225A surges - ideal for motor/generator testing.
