Fonte de alimentação MITEL para série SIP 6800i — adaptador 48V DC para telefones VoIP

External 48V DC power supply designed for MITEL SIP 6800i series VoIP phones. This adapter provides a stable low-voltage DC output to power compatible SIP desk handsets when Power over Ethernet (PoE) is not available. The unit is intended for office and business environments where reliable voice communication and consistent phone feature availability are required. It connects to the handset's power input and supplies the required voltage to maintain call stability and device operation.

Advantages

The power supply delivers a constant 48V DC output with built-in protection against common electrical issues, ensuring uninterrupted operation of MITEL SIP 6800i phones. Its compact external design simplifies installation and reduces the need for internal power modules. The adapter's compatibility with the SIP 6800i series minimizes configuration changes and supports standard handset functionality without relying on network-based power.

Key specifications

• Output voltage: 48V DC
• Intended use: external adapter for compatible SIP desk phones
• Form factor: compact external power brick with cable
• Protection features: overcurrent and short-circuit protection (built-in)
• Environment: indoor use, office and business installations

How to use

Connect the adapter to a standard AC power outlet using the supplied mains lead, then plug the DC output connector into the power input on the MITEL SIP 6800i handset. Ensure the outlet provides the correct local voltage and that connections are secure before powering the device. After connection, the phone should receive power and initialize normally; consult the handset's user guide for any device-specific startup procedures.

Recommendations

Use the adapter in a ventilated indoor location away from moisture and extreme temperatures. If the handset will be used in a network environment that supports PoE, consider using PoE for cable consolidation, but keep this adapter as a backup power option where PoE is not present. Replace the adapter if physical damage, unusual noise, or overheating is observed.
