Low voltage
SZR – Reserve switching cabinets
Application
- Sustaining power supply in facilities and networks requiring continuity of power supply, due to the sensitive location and functions performed.
- Switching power sides, according to the set configuration.
- Meeting power supply reliability requirements.
- Electricity distribution and circuit protection on the LV side.
- Protection of electrical equipment against the effects of short circuits and overloads.
Housing
- Thermosetting plastic: The housing is made of SMC plastic with IP 44 or 54 in II protection class, with flammability class from HB to V0, in RAL 7035 color, with the possibility of additional painting to ensure temporary resistance to environmental effects and UV radiation.
- Aluminum OU-2: Housing made of aluminum sheet (joining by welding or riveting). Powder coated in any color. Dimensions adapted to the type, amount of equipment and individual customer needs. The housing has a high resistance to degradation, environmental impact and UV radiation. The housing is made in protection class I or II. Class II protection is achieved by applying an additional insulation layer, permanently lined on the inner and outer surfaces. The thickness of the layer ensures the proper degree of insulation.
- Ventilation allows constant air flow through the use of a ventilation labyrinth, while eliminating the ingress of dirt and the accumulation of water and moisture. Doors having internal hinges with anti-burglary catch and multi-point locking, basquil lock lockable with padlock or system cylinder.
Primary and backup power source
- Depending on the power present; contactors or circuit breakers / disconnectors, additionally equipped with protection in the form of fuse disconnects: 20 to 450A – contactors; 40A to 6300A – circuit breakers and disconnects.
- Clutch – provides safe power switching depending on the power present: contactor or circuit breakers/motor switches.
- Automatic control system SZR – prepared to operate contactors or circuit breakers, provides automatic switching between primary and standby power, setting any delay and time setting, switching interlocks to avoid parallel operation.
- Automation systems used: PRE (own module), MA-0A, MSR, MAX, others. All switches are set according to scheduled diagrams. The delay time setting can be adjusted in the range of 0,2-30s and 20-180s. It is possible to control automatically or manually.
Frequently asked questions
What is your delivery time?
Standard delivery time is approximately 6-8 weeks depending on the order. Please contact us to arrange a more detailed delivery date.
What effects do your charging stations have?
We offer an extensive range of products, encompassing both AC and DC EV chargers featuring diverse equipment configurations and power outputs. The power spectrum of our EV chargers includes:
- AC 3.7-43 kW
- DC 40-480 kW
Who installs charging stations?
Charging stations are only installed by Swedish certified electricians.
How fast do your stations charge?
The fastest DC chargers can charge a car in up to half an hour. Charging time for electric vehicles depends on:
- EV charger power
- battery capacity
- the power of the converter installed in the car.
Which station is best for private use?
The best choice for private use are small stations such as:
- EVB E-wall - mounted in the wall not only makes it much easier to use, but also blends almost seamlessly into the façade and improves its aesthetics.
- EVB Wallbox 2M AC - it can be hung on the wall in the garage, thanks to which it takes up little space and can charge two cars at the same time. Charging point power up to 22 kW.
How is the advertising content on EVB Adverts charging stations managed?
Advertising content on EVB Advert chargers is managed using the Digital Signage Android Player. It is an extremely functional software for remote management of content on the monitor. The software allows you to manage content from any place with Internet access - just log in to the relevant website, upload videos, images, webpages, RSS feeds, remote content, divide the screen into any number of screen areas of any size and position, and much more. The big advantage of Central Stacks software is that the server is in the cloud, so the client does not need to install and maintain it on its side, and therefore the content of any connected media can be managed anywhere and on any device by logging into the server through a web browser.
Our billing model for Central Stacks licenses is also very simple and transparent, unlike many other systems on the market, since the annual license price already includes all the costs incurred by the customer for the system including server maintenance, etc., so at each stage of the project the customer knows exactly how much it will cost him to expand the DS network with additional installations.
How to settle accounts with charger users?
Our stations are equipped with a measurement and billing system, which enables quick settlement with the customer. Settlements are made via mobile applications, RFID cards or a payment terminal.
What is the difference between charging a car with AC and DC?
In the simplest terms, the key distinction lies in the charging speed of the vehicle. In the case of alternating current (AC), the EV is usually charged slower compared to direct current (DC), because the alternating current needs to be converted, and the charging speed depends on how much current the wallbox can supply and how much current the vehicle battery can handle. Charging with alternating current is the most popular method of charging electric vehicles and is widely used, among others, while charging at home.
DC charging, on the other hand, is a faster charging option often used in public places using chargers with higher power outputs. Unlike AC charging, DC charging delivers direct current to the vehicle battery without a conversion process. The type of charging station you should install depends entirely on your needs and specific requirements. In public areas such as parking lots, a combination of AC and DC charging can provide a pragmatic solution to meet the diverse needs and preferences of different guests.
