1500Vdc Firefighter Solar PV DC Switches with remote operation and diagnostic output.
Pennine Components Ltd are the UK Distributor for Bremas Ersce SpA.
We are pleased to announce the launch of Bremas’s DM Series of Motorized Solar PV Disconnect Switches, which are designed to allow the safe isolation of the DC circuit in case of emergency.Incorporating Bremas’s patented rotary contact technology, these Motorized Isolators offer unrivalled levels of flexibility and reliability.
The standard Switch may be specified with between 2 Poles (1 MPPT) and 10 Poles (5MPPT), with PV1 current ratings per string of up to 60A at 1000Vdc, or 30A at 1500Vdc.
Shut down occurs via the manual operation of a safety switch, or if there is a sustained AC Mains failure, or if the temperature exceeds 100C. When stable AC Mains is restored, the Isolator will re-connect the power.
A pulsed relay output allows diagnostic signalling of system conditions to a central PLC.
The standard DM Series allows the user to integrate the individual components, consisting of the DC Isolator (with pre-fitted Motor and status indicator), which can be DIN Rail or Panel mounted, and a Control PCB into their own control system.
Bremas are also offering a pre-assembled solution, the FB Series, Isolating up to 16 Poles (8MPPT).
Features:
- Motorised DC Isolator with 2 to 10 Poles (1 to 5 MPPT) and built in status monitoring contacts.
- Current ratings PV1 per MPPT up to 60A at 1000Vdc, Thermal 50A to 60A.
- Current ratings PV1 per MPPT up to 30A at 1500Vdc, Thermal 50A to 60A.
- Patented rotary contact technology with proven worldwide installation.
- PV1 and PV2 ratings, IEC EN60947-32015/A2 Annex D certified.
- Base/DIN Rail mounting or Panel mounting.
- Mechanical Status Indicator ON /OFF.
- Electronic Control board to control 1 or 2 Isolators, with optional DIN Rail bracket.
- LED status monitoring, with diagnostic relay output.
