PRESSURE SUPPLY UNITS SERIES DH 2000 HYDRAULIC POWER PACKS & HYDRAULIC UNITS

Transcription

1 PRESSURE SUPPLY UNITS SERIES DH 2000 HYDRAULIC POWER PACKS & HYDRAULIC UNITS The Dellner hydraulic power pack series DH 2000 are available in four different models, each with several different options. The main functions of the different models are as follows: DH 2100: On/Off unit with an optional accumulator. DH 2200: Unit with Separate function available as an option to make it possible to pressurise two braking systems individually and independently. Other options are an accumulator, hand pump and pressure switches. DH 2300: Unit with proportional s that gives the possibility to achieve a controlled operation by programming any kind of braking curve, controlled by an optional PLC in an electrical terminal box. Other options are an accumulator and hand pump. DH 2400: Unit with Double control s for critical applications such as overhead cranes, etc. Other options are an accumulator, hand pump, pressure switches and additional filter unit. All four models can be delivered with optional hydraulic s and electrical terminal boxes. The optional s/boxes for all four models have the same dimensions. The electrical terminal boxes can be delivered with optional rapid connectors and/or fireproof cables.

4 DH 2300 DH 2300 is a unit with proportional s that gives the possibility to achieve a controlled operation by programming any kind of braking curve, controlled by an optional PLC in an electrical terminal box. Other options are an accumulator and hand pump. INTERFACE / CONTROL Customer supplies control signal(s) and DH 2300 generates one of following alternatives: A controlled braking curve A number of different pressure settings (braking forces) depending on the different control signals (ma) supplied by customer.
