SPM-D11 Series Load Share Synchronizer Load/var sharing Generator protection Synchronization for one circuit breaker Frequency, phase, and voltage matching Selectable types of control output Digital display of generator and bus values Real power control Power factor control PC and front panel configurable Microprocessor technology for flexible and reliable operation CE marked UL/cUL listed APPLICATIONS The SPM-D11 is a microprocessor-based synchronizer designed for use on one or three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D11 synchronizer provides automatic frequency, phase and voltage matching using either analog- or discrete output bias signals. It combines synchronizing for one circuit breaker, load and power factor control or isochronous load sharing and generator protection. DESCRIPTION Synchronizing Phase match or slip frequency synchronization with voltage matching Two-phase sensing of generator and bus Selectable operating modes like SPM-A (Run, Check, Permissive, and OFF) Synchro-check possible Synchronization time monitoring Load/var sharing Mains parallel operation Real power control True RMS power calculation Generator real power setpoint by parameter (2 values) or via 0/4 to 20 mA Soft unloading Power factor control Power factor setpoint by parameter Power limit value with relay output Isolated operation Frequency control Voltage control Dead bus operation Closing of breaker on demand DESCRIPTION Protection ANSI # Single-phase CT sensing for generator Two-phase sensing of generator voltage Generator over-/undervoltage (59/27) Generator over-/underfrequency (81O/U) Generator reverse/reduced power (32R/F) Generator overload (32) Control outputs LSXR Package Analog bias outputs for voltage and speed freely configurable for all levels (+/-1 V, +/- 3 V, 0 to 5 V, 0.5 to 4.5 V, +/-10 V +/-5 V, 0 to 20 mA, +/-20 mA, and much more configurable) Speed bias output configurable as 500 Hz PWM output and adjustable voltage level Two raise/lower outputs configurable for either speed or voltage Operating Features Two-line Liquid Crystal display for operation and alarm indication Synchroscope Indication of control activity and breaker state Multi-level password protection for parameters Configuration directly or via PC English or German language adjustable FURTHER SPM-D SYNCHRONIZERS The SPM-D10 Series provides two-phase generator and bus measurement refer to product specifications 37297 for more information The SPM-D10/YB Series provides three-phase generator and bus measurement
