H-Series Electrodynamic Shaker Systems

The H Series provides an intermediate force range of vibration test systems consisting of the SAI Series Class D power amplifier, H560 electrodynamic shaker, DC field supply, and remote cooling blower. Systems are provided as complete packages including EMI shielded console with 3-phase line filtering, interface cabling, integrated safety interlocks, and full featured interface panel for the power amplifier. All systems are direct coupled for maximum rated performance and require no transformer reconnections or switching circuits. The performance of the H Series supports a wide variety of vibration test applications including product development and design conformance, qualification and certification, and production screening.

Air Cooled

All of the H560 Series configurations are totally air cooled, an important feature that reduces the cost of installation and operation. Both the SAI Series power amplifier and the H560 electro-dynamic shaker are cooled by forced air. Quiet mode circuitry and sound enclosures for the blower are available for Buzz, Squeak & Rattle applications.

2 inch (51 mm) and NEW 3 inch (76 mm) Displacement

The H560 Series shaker is rated for 2 inch displacement, a requirement for many transportation vibration specifications and for long duration shock pulse testing. A 3 inch (76 mm) displacement option is now available for the H560B-24 Shaker.

Internal Load Support

800 lbs (362 kg) internal pneumatic load support including automatic armature centering is provided as standard on the H560B-12, with 1,360 lbs (618 kg) included for the H560B-16, and 1,500 lbs (680 kg) for the H560B-24.

Rugged, Lightweight Armatures

Cast from either a high strength magnesium or aluminum alloy, the H560 Series armature incorporates a multi-ribbed table for maximum stiffness and minimum weight. For higher frequency applications, the "A" version system is available. The construction and low weight of these armatures allow greater versatility for applications requiring a high g level testing; testing large, heavy payloads or high frequency testing. The H-series now offers three armature sizes to allow selection of the best performance to payload weight ratio.

Head Expanders

For applications involving large and heavy payloads, the H560 can be fitted with an optional 24 inch (610 mm) or 30 inch (762 mm) head expander. Designed for 2,000 Hz operation, these head expanders include integral linear bearings and additional pneumatic load support up to 2,000 lbs (907 kg). Many other expander sizes are available.

Combined Environment Testing

The H560 Series is very popular for applications requiring combined environment testing, specifically combinations involving temperature, humidity and vibration. All three base options support combined environment testing allow simple integration with chambers manufactured by all of the leading thermal chamber companies worldwide. Thermal barriers, an oil conditioning system for slip table, and remote system startup from an external contact closure are available.
