Why use Load Banks in Data Centers?
Most data centers have a back-up UPS systems and diesel generators to supply power if the grid fails. Regular maintenance is vital in ensuring reduced down time in data centers, in the US an average cost of one minute of downtime is estimated at $7900 USD. Load banks are the most effective way to test and stress electrical systems for maintenance and periodic testing purposes. A variety of load test types can be configured for specific maintenance purposes and reports will identify issues in systems that can be replaced or fixed to ensure efficient operation.
1. Resistive type of load, PF = 1.0. Stainless steel sheathed elements manufactured from high grade magnesium oxide.
2. Rated testing voltage : AC 3P4W, 110-480V 50/60 Hz. standard, special one on request.
3. Cooling mode: Forced air-cooled, fans mounted on the side of the load bank blow horizontally. Testing power or external utility power supply for fans.
4. Working mode: Load step control
Total testing capacity ranges from 0kw to the max consisting of 10kw, 20kw, 50kw, 100kw load setting switches plus a 0-10kw fine-tuning knob. From 0kw to the max, any load combination is achievable. Load step resolution is 10kw.
5. Load bank features world-famous components to ensure reliable performance and longer service life including:
SCHNEIDER contactors.
Siemens switches, knobs and indicators.
ABB Circuit breakers.
OMRON intermediate relays.
PHOENIX terminal blocks.
6. Parameter measuring accuracy grade: 0.3
7. Load control accuracy: ± 5%.
8. Load bank protections: Over heating protection, cooling fans failure protection and over load protection with alarm.
9.Control mode: Two control modes available:
A)Local manual control;
B)Optional: Manual control via a remote control panel (max control distance is 30m).
10. Parameter display and measurement:
Control panel contains a LOVATO Multifunction Electricity Meter displaying voltage, current, load power, reactive power, apparent power, power factor, frequency etc.
(Optional: A professional generator tester displays and measures all sorts of steady, dynamic parameters as well as harmonic wave, can be connected to a PC for data recording and test report printing). ”
11. Operating environment:
Altitude: ≤ 3000m above sea level. Ambient temp: -10~+50 ℃
Relative humidity: ≤ 80% ventilated environment without explosive or corrosive dust. Not allowed to use in rainy outdoor environment.
