December 2024 Grace Technologies 3000Vdc test port
Testing voltage for DC systems up to 3kV shouldn’t be a gamble with safety. If you’re working in utility-scale solar power, electric vehicles, electric rail systems, or EV charging stations, you are aware of the danger. Traditional methods for testing voltages above 1000 VDC demand specialized equipment, expose your team to increased electrical hazards and prolong Lockout/tagout (LOTO) procedures. The Chek Volt 3000 from Grace Technologies allows Utility Scale Solar Farms to safely test up to 1500 VDC in combiner boxes and inverters during maintenance, without having to open the control panel, reducing arc flash and electric shock risks, speeding up the Lock out tag out process. The presence of voltage may be confirmed by visual indication by LED or by probing with a voltmeter. Incorporating a built in 10:1 Potential Divider, and protective series resistor, the voltage is reduced to a safer level that may be tested with a standard voltmeter. So 1500Vdc would give 150Vdc at the test point.
October 2024 Bremas 1500Vdc Remote Operation Firefighter DC Disconnector Switch.
We are pleased to announce Bremas’s new DM and FB range of DC Disconnector Switches, which allow up to 10 Poles (5 PV Inputs/MPPT) to be remotely disconnected in case of emergency.
The Switches can be shutdown manually via a Pushbutton with N/C contact, or set to Auto-Disconnect if there is a sustained AC Mains failure, or the temperature inside the enclosure exceeds 100C.
The standard DM Series allows the user to purchase the individual system components to integrate into their own panels. The FB Series is supplied as a pre-assembled solution in a box, for up to 8 Poles (4 Inputs/MPPT), prewired with MC4 connectors or without.
The system components consist of 3 items:
1 DC Isolator Switch
The switch is based on Bremas’s next generation, patented rotary contact technology, featuring:
• 2 to 10 Poles (1 to 5 MPPT), with status monitoring contacts.
• Colour coded Terminals +V Brown, and -V Black.
• 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.
• Switch proven with worldwide installation.
• PV1 and PV2 ratings, IEC EN60947-32015/A2 Annex D certified.
• Base/DIN Rail mounting, panel mounting with 4 screws, or Single hole panel mount.
2 Motorised Actuator
This operates the switch, and can be supplied with an optional visible status indicator.
3 Electronic Control Board.
This manages the control of the actuator, and holds back up charge in the event of a power cut, sufficient to operate the Actuator to the Off position, and a temperature sensor.
