Developed and approved for marine use, we have concentrated the design within the following areas: • Easy to configure and operate • Cost effective • Versatile programming facilities • Various interfaces for remote monitoring and data acquisition SIGMA Modules: No matter what...

S6000 will provide a simple, yet power- ful solution to a full scale control system. Such a system will provide protection, auto-synchronization, active/reactive load sharing, and indication/SCAD A A single variant supports nominal Secondary CT current must be specified Marine approval The S6000 is designed to comply with marine requirements. The design of the circuitry and metal casing provides the best possible protection from EMC and environmental stress. • Short circuit protection • Over current protection • Overload protection • Reverse power protection • Excitation loss protection • Load...

lization, voltage stabilization, automatic synchronization and active/reactive load sharing. The PID algorithms provide very fast regulation with very little overshoot. The RS485 MODBUS-RTU connection provides easy interfacing to SCADA systems and PLCs. Measured and calculated parameters are easily accessed by any device capable of operating as a MODBUS master. Configuration parameters can also be accessed and altered through MODBUS-RTU. • 3 phase measurements • Voltage matching • Frequency control • Auto synchronization • Active load sharing • Voltage control • Reactive load sharing • Dead bus...

SIGMA S6500 UI Module (optional) S ­ ELCO T4500 Auto Synchronizer is c ­ onnected to an input (FREQ. IN) of the S6100 SIGMA S/LS modules in order to align the frequency for synchronizing. When the “Sync On” contact is closed, the external frequency signal from the T4500 Synchronizer will be active and all internal frequency controls of the S6100 S/LS modules are disabled, as the frequency is now determined by the other busbar section, e.g. the shaft generator or the grid. This is an example of using the well proven existing SELCO units with the SIGMA system. • Integrated multimeter • SIGMA user...

We are SELCO Since the origin in 1960, SELCO technology has provided the electrical power generation market with high class equipment, living up to major international standards. SELCO manufactures and supplies electronic relays and microprocessor based equipment for control, monitoring and protection of medium sized generators in parallel operation. Primarily the products are used for generators on board ships and in compact landbased power stations where operation in parallel with the grid (utility) may also be a requirement. SELCO also manufactures a wide range of alarm monitors, indicator...
