Unit 3 Compliance Ltd

The company provides laboratory testing, fault remediation, and environmental verification capabilities:

• EMC Emissions Testing: Radiated emissions testing from 9 kHz up to 18 GHz, and conducted emissions measurements from 9 kHz to 30 MHz on single-phase and three-phase mains ports up to 32 A and Ethernet interfaces, as well as EN 61000-3-2 harmonics and EN 61000-3-3 flicker evaluation.
• EMC Immunity Testing: Electrostatic discharge (ESD) to 16.5 kV per EN 61000-4-2, radiated RF immunity from 80 MHz to 2.7 GHz at 10 V/m per EN 61000-4-3, electrical fast transients (EFT) up to 4 kV per EN 61000-4-4, and surge testing up to 6 kV per EN 61000-4-5.
• Vibration & Mechanical Shock Testing: Dynamic testing using an LDS V724 electro-dynamic vibration shaker (frequency range 4 to 2000 Hz, maximum sinusoidal acceleration 94 g / 6.7 kN peak force, random acceleration 50 g / 5.3 kN RMS, maximum displacement 25 mm pk-pk, and maximum velocity 1.78 m/s) for resonance search, random vibration, and shock testing.
• Design for EMC & Compliance Consultancy: Pre-compliance testing, regulatory roadmapping, documentation compilation, and circuit schematic and PCB layout reviews prior to prototyping and production runs.
