How do Delab products improve energy efficiency?
Delab’s power factor controllers and digital power meters help optimize energy usage by monitoring and managing the power factor in electrical systems. This helps reduce energy wastage, lower operating costs, and ensure compliance with energy efficiency standards.
What types of relays does Delab offer?
- Earth Leakage Relays: Protect against electrical faults caused by leakage currents.
- Overcurrent Relays: Safeguard electrical systems from excessive current.
- Differential Relays: Detect differences between live and neutral currents to prevent faults.
- Under/Over Voltage Relays: Protect systems from damage caused by voltage fluctuations.
What is the difference between a DELAB Power Digital Meter, Digital Earth Leakage Relay, and Earth Fault Relay?
- Power Digital Meter: Measures and displays electrical parameters (V, A, kW, kWh, PF, THD). It’s for monitoring or analytics only.
- Digital Earth Leakage Relay (ELR): Detects low-level leakage current (mA) to earth for shock/fire prevention and trips a breaker/contactor.
- Earth Fault Relay (EFR): Detects higher ground-fault current (A) on feeders/busbars for network protection or coordination and trips upstream breakers.
