Power Supplies — For Security Systems in Tbilisi
Power Supply Units are special electrical devices that provide stable and reliable power for security systems — IP cameras, AHD/TVI/CVI cameras, DVR/NVR recorders, access control systems, electric locks, alarm panels, intercoms in Tbilisi and throughout Georgia. These power supplies are ideal for any security facility requiring stable 12V/24V power — switching technology (high efficiency 85-95%, low heat), protection functions (overcurrent, short circuit, overvoltage, overheating), UPS function (battery backup power, automatic switching). LAGI offers power supplies with full functionality: 12V/24V output voltage, 1A-30A output current (12W-720W power), switching technology (Switching Mode), 85-95% efficiency, protection functions (OCP, SCP, OVP, OTP), UPS function (battery charging, automatic switching), multiple outputs (4-18 channels), LED indicators (Power, Fault, Battery), metal housing (protection, cooling), DIN Rail mounting. All models comply with CE standard.
Main Functions of Power Supplies
- Stable output — precise 12V/24V voltage (±5%), no fluctuations, ideal for sensitive devices.
- Switching technology — high efficiency 85-95%, low heat, compact size.
- Protection functions — OCP (overcurrent), SCP (short circuit), OVP (overvoltage), OTP (overheating).
- UPS function — battery charging (12V/7Ah-12Ah), automatic switching during power outage, 2-8 hours backup time.
- Multiple outputs — 4-18 channels, independent protection per channel (Fuse), simple connection.
- LED indicators — Power (power on), Fault (problem), Battery (battery status).
FAQ — Frequently Asked Questions
Transformer power supply — old technology, uses transformer (220V → 12V), powerful, heavy (1-5kg), low efficiency (50-70%), strong heating, large size. Switching power supply — modern technology, uses switching converter (Switching Mode), light (0.2-1kg), high efficiency (85-95%), low heating, compact size, protection functions (OCP, SCP, OVP, OTP). Advantages of switching: high efficiency (less power consumption, less heating), compact (simple installation), light (transportation), protection functions (safety), wide input range (100-240V, ideal for unstable network). Recommendation: switching power supply — modern choice (better quality, efficiency), transformer — old technology.
Power supply capacity calculation — 1) Find each camera consumption: IP camera (PoE) — 5W-15W (depends on model, IR illumination), AHD/TVI/CVI camera — 3W-8W, PTZ camera — 20W-50W. 2) Calculate total consumption: example: 8× IP camera (each 10W) = 8 × 10W = 80W. 3) Add 20-30% reserve: 80W + 20% = 96W → choose 120W power supply (10A @ 12V). Formula: power (W) = voltage (V) × current (A), example: 12V × 10A = 120W. Tips: always choose more powerful power supply (20-30% reserve), consider IR illumination consumption (night consumption increases), use UPS power supply (backup battery during power outage), don't overload power supply (will reduce lifespan).
UPS power supply (Uninterruptible Power Supply) is power supply with built-in battery backup power — when electrical network works → UPS power supply receives energy from network, charges battery, supplies stable power to devices. When electrical network shuts down → UPS automatically switches to battery power (0.01 seconds), devices continue working (2-8 hours, depends on battery capacity and consumption). Why needed: security systems must work 24/7 (during power outage most needed), cameras continue recording (no video lost), access control continues working (doors won't lock), alarm continues monitoring. Battery capacity: 7Ah (2-4 hours), 12Ah (4-8 hours), 17Ah (8-12 hours). Recommendation: for all security systems — UPS power supply (mandatory).
