Cofi Ignition transformer TRS830P

The Cofi TRS830P is a high-voltage ignition transformer used in the ignition circuit of burners and boilers. It steps up the mains voltage to create a spark across the electrode gap during the ignition sequence. This model operates with a primary voltage of 230 V and features a silicone-insulated ignition cable. It is identified by SKU TRS830P and catalogue number 309.820.014.

When selecting a replacement ignition transformer of this kind, verify that the secondary voltage and current, primary voltage (230 V, 110 V, or 24 V), and duty cycle match the original specifications. The mounting arrangement, terminal type, and ignition cable connector pattern must also be compatible. Always confirm the exact parameters against the burner manufacturer's documentation before ordering.

Common failure modes include a hardened or cracked ignition cable that leaks the spark to earth, which may appear as a transformer fault. The equipment may fail to ignite or exhibit intermittent sparking. Check the ignition cable for damage and verify the transformer's output with a suitable tester.
