Born as a DSR evolution, it is building is extra feature such as single and three phases sensing automatic detection, higher flexibility in remote voltage control, soft start and a voltage precision of 0.5% in static condition.

The connectors for connection to and from the power generator and communications module are located on the DER1 regulator. The supervision unit can be made up of a personal computer, another “synoptic” device or both; it does not have the function of controlling the system in real time, but allows programming and visualisation of all operational parameters of the DER1.

Since the regulator is designed to control many different types of generators, it must be appropriately configured to obtain the best performance; most of the settings are stored in a non-volatile integrated memory (EEPROM)

Features

◆ Power connections through 20 poles Fast-On connector

◆ Protection of power winding with 5A fast acting fuse

◆ 0 ÷ 2,5Vdc or -10 ÷ +10Vdc external voltage for analogical remote control of output voltage

◆ Remote control of output voltage through external potentiometer (from 25Kohm to 100Kohm)

◆ Underspeed protection with adjustable threshold and slope

◆ Overvoltage and undervoltage alarms

◆ Excitation overcurrent protection with delayed intervention

◆ Underexcitation alarm/loss os excitation

◆ Management of temporary short circuits (start up of asynchronous motors)

◆ Open collector output (not insulated) signalling some allarm intervention with programmable activation in respect of each alarm and possibility of the intervention delay and selectable active level

◆ Allarm conditions storage (type of alarm, number of events, duration of the last event, total time)

◆ Memorization of the regulator operation time

◆ USB communications interface (with optional USB2DxR module)
