What is Flatpack2?
The Flatpack2 module is a hot-pluggable, digitally controlled switch mode power supply. Flatpack2 DC power systems are implemented by mounting the rectifiers in 23” or 19” power shelves (4 modules across).
What is Eltek rectifier?
Eltek V Series Rectifiers are reliable, efficient, and cost-effective rectifier modules. They provide unprecedented power density and in a truly compact, plug-and-play format. Eltek V Series Rectifiers have a wide range of available voltages, power ratings, and system from factors, Read more …
What is Delta Rectifier?
A rectifier converts alternating current (AC) to direct current (DC) and provides the power necessary to charge batteries. Delta’s rectifiers are easy to install, as their connectors are located at the rear and are hot-pluggable. Fan cooling with speed control renders operating almost silent.
What is the status if the controller led of Eltek SMPS is of amber Colour?
Action
| LED | Color | Description |
|---|---|---|
| OUTPUT OK | Blue | Power supply is not functioning. |
| NO AIRFLOW (Original power supply only) | Amber | Power supply is inserted, but airflow around the power supply is not sufficient. |
| CB OFF | Amber | Power supply is functioning, but the circuit breaker is off. |
Why battery bank is used in substation?
Battery rooms are also found in electric power plants and substations where reliable power is required for operation of switchgear, critical standby systems, and possibly black start of the station. Very large utility batteries may be used for grid energy storage.
Is standard for battery charger?
This part of IEC 60335 deals with the safety of electric battery chargers for household and similar use having an output not exceeding 250 V ripple-free direct current, their rated voltage being not more than 250 V. This Specification applies to a battery charger for the charging of 1 nickel-cadmium cell.
Why is DC supply used in substations?
The main reason for using DC supply in substation or power stations is to provide a continuous power supply to the control circuit. DC is a reliable source of power supply because it can obtain from batteries. So during power failure also, we have to provide the continuous power supply to the control circuit.
Which transformer is used in 33 11kV substation?
To step down the 33kV primary voltage to 11kV suitable for distribution purpose. One 33kV/0.415 auxiliary transformer was also needed to supply the substation with reliable AC power.
What are the different types of battery chargers?
There are two different types of battery chargers on the market today – Timer Controlled chargers and Smart chargers (also called Intelligent chargers), each for a different budget, (Timer Controlled are less expensive), but more importantly, using two different technologies.
How fast does a fast charger charge?
Qualcomm Quick Charge (Samsung, LG and other smartphone and tablet devices): Quick Charge 3.0-compatible devices charge from zero to 80% in 35 minutes* Quick Charge 4.0-compatible devices charge from zero to 50% in 15 minutes*
Why 110v DC is used in substation?
The main reason for using DC supply in substation or power stations is to provide a continuous power supply to the control circuit. If a power failure occurs, all devices will stop working then we cannot check the fault status, status of the circuit breaker and relay.
Why battery is used in substation?
A substation battery charger ensures all the essential electrical systems in a substation continue to operate in the event of a power outage. In a normal functioning system, the batteries provide very little current. A continuous load current maintains a constant charge on the battery.
What are the applications of the flatpack2 power supply?
The Integrated 19” 2U power supply is built around the Flatpack2 rectifier and designed for applications such as switchgear, telecom, emergency lighting and alarm systems. The Integrated 19” 2U power supply is built around the Flatpack2 rectifier and designed for applications such as switchgear, telecom, emergency lighting and alarm systems.
What is the efficiency of the flatpack2 DC rectifier?
The Flatpack2 48V/3000W SHE is contributing to setting the new industry standard for efficiency in the DC power market. With an efficiency of 97.8% the Super High Efficiency (SHE) is a premium rectifier particularly suitable for markets and applications where the energy is costly.
Do you need to change the air filter in an indoor flatpack?
When installed in outdoor enclosures, it is important to keep the door closed during operation, and replace the filters on a regular basis. Indoor installations in dusty or humid areas require appropriate air filtering of the room, or filtering of the air entering the DC power system.
