TTW-400 - 4 Feet Table Diameter

TTW-400 turntable

4 Feet Manually Operated Turntables

  • TTW-400 manually operated EMC turntable, 4-foot diameter — a low-profile, above-ground motorized rotation platform for spinning the equipment under test (EUT) during commercial EMC radiated emissions testing.
  • Finds the worst-case emissions angle — rotating the EUT through a full 360° lets the operator identify the position at which the equipment radiates maximum electromagnetic interference, as required for radiated emissions compliance.
  • Bidirectional rotation from a handheld remote switch — a reversing-drum remote turns the turntable clockwise or counterclockwise from outside the measurement area, on a 9.8 ft (3 m) extension cable.
  • Manual toggle-switch control on the motor box — the TTW-400 also supports direct manual operation via a toggle switch mounted on the table's motor box.
  • Motor and gear-reduction rotation drive — the drive pairs an electric motor with a gear-reduction unit for smooth, controlled 2.1 RPM rotation under load.
  • Supports desktop or floor-standing equipment up to 1000 lbs — the 4 ft (1.2 m) platform holds and rotates EUTs weighing up to 1000 lbs (455 kg) at just 9 in (23 cm) table height.
  • Non-conductive, weatherproof construction — built from non-conductive weatherproof materials so it adds no reflections to the measurement and is equally suited to indoor and outdoor test sites.
  • Optional loading ramp available — any optional ramp can be ordered with the turntable to roll heavy equipment onto the low-profile platform.
