Swept-sine resonance search and dwell to 211 lbf (0.94 kN) peak and 100 gn, across the widest usable band in the V555/V650/V721/V780 family.
Light PSD screening and qualification of circuit boards, sensors, and small assemblies to 143 lbf (0.636 kN) rms.
Two-millisecond half-sine pulses to 281 lbf (1.2 kN) with the standard payload, at 10% pre- and post-pulse.
What it is used for
- Automotive component testing: sine and random vibration testing of small components.
- Electronic assembly testing: vibration screening and qualification of circuit boards and small assemblies.
- Modal and structural analysis: structural excitation with a wide usable frequency range from DC to 6,300 Hz.
- Fatigue and resonance testing: resonance searches and dwells on lightweight test articles.
- Velocity transducer or high-speed actuator: using the shaker itself as a transducer or fast actuator.
- In-house testing and calibration: routine vibration checks and sensor calibration work.
Key features
- Lightweight, high-performance armature: the 2.07 lb (0.94 kg) moving element delivers 100 gn sine acceleration and 59.1 in/s (1.50 m/s) velocity.
- Robust, lightweight suspension: provides torsional and transverse stiffness with minimal impact on system acceleration.
- Wide frequency range: armature resonance at 4,850 Hz and a usable range from DC to 6,300 Hz, the widest in the family.
- Vertical and horizontal operation: trunnion-mounted for either test axis.
- Compact, quiet amplifier: the rack-mount LPA1000 is a Class B linear amplifier with a signal-to-noise ratio above 95 dB and a sound power level of 49 dBA at 6.6 ft (2 m).
- Armature interface: 4.33 in (110 mm) armature with one center insert and eight equispaced inserts on a 3.5 in (90 mm) pitch circle, in 1/4 UNF or M6.
Why engineers pick it
The V555 system
- LDS LPA1000 linear power amplifier: 961 VA rated output into 4.0 Ω (1,296 VA maximum), single-phase input of 100, 120, or 230 V.
- LDS FPS field power supply: supplies DC power to the shaker's field and degauss coils and a switchable 0.75 kVA output for the cooling fan. The FPS is required when driving the V555 with the LPA1000.
- Cooling fan: single-phase 230 V, 50 Hz, or single-phase 120 V / 230 V, 60 Hz.
