This unit is a part of the Woodward Inc. lineup of Digital Synchronizer and Load Control modules or DSLC modules. Woodward Inc. is the oldest and leading manufacturer of these types of devices in the world. The DSLC line is developed as a microprocessor-oriented synchronizer and control unit, based on functions with three-phase, Alternating Current generators.
This unit is listed with the numerical identification code 9905-363. Its unique specifications include the speed bias output of +/- 3.0 V/DC. This indicates that this model is compatible with the standard Woodward digital and analog speed controls, via the auxiliary inputs. The voltage input of this DSLC module ranges from 150 to a maximum of 300 V/AC.
The 9905-363 unit is designed with an open delta PT Configuration. This is the switchgear configuration primarily used in North American hardware, consisting of two PTs between A-B and B-C phases, with the B phase grounded to the switchgear ground.
The standard Woodward specifications include an operational temperature range that goes as cold as -40 C to as hot as 70 C (-40 to 158 F). The relative humidity that the metal of this unit can handle before being affected by excess water vapor is at a threshold of 95%, at 38 C (100 F).
The 9905-363 DSLC unit is available from us here at AX Control Inc. We offer a wide range of products available from new surplus products, to reconditioned, used materials. Repairs are handled by our staff of on-site technicians.
