Unison 9060040-1G Ignition Exciter 100VA 230VAC

Unison 9060040-1G Ignition Exciter 100VA 230V-AC

The Unison 9060040-1G Ignition Exciter is a heavy-duty, industrial-grade capacitive discharge ignition generator engineered specifically for reliable light-off sequences in land-based gas turbines, marine propulsion systems, and large industrial boilers. Driven by a high-output 100VA power rating at 230VAC operational input, this unit steps up low-voltage supply currents into high-energy pulses ranging from 15 kV to 20 kV.

Constructed inside a rugged, hermetically sealed steel enclosure and filled completely with a vibration-dampening epoxy potting compound, the 9060040-1G provides unconditional resistance against thermal cycling, extreme moisture, and physical shock. It features an intelligent internal diagnostic monitoring circuit that flags spark degradation or voltage drops in real-time, protecting critical machinery down the line from wet-start conditions.

Model Information:

• Brand: Unison Industries
• Model / Manufacturer Part Number (MPN): 9060040-1G
• Alternative Part Numbers / Cross-References: 90600401G, 9060040-1, FSCM-59501 (Series Family Equivalent)
• Product Type: Solid-State Dual-Channel Industrial Ignition Exciter

Features

1. Dual-Channel Asynchronous Firing: Two totally isolated, independent outputs fire asynchronously to ensure spark delivery even if one ignition line or spark plug develops a ground fault.
2. Integrated Diagnostic System: Uses an active internal sensor circuit that automatically energizes an auxiliary dry-contact relay when the output voltage drops below ~15 kV or the spark rate falls below 1.0 spark/second.
3. Fully Potted Enclosure The high-strength steel enclosure is fully potted in a sophisticated polymer epoxy protecting interior components from moisture, dust and turbine deck vibration.
4. High Energy Load: Capable of 100VA apparent power consumption to reliably supply stable, high voltage (15kV-20kV) arcs for heavy fuel and turbine start-ups.

Technical Details: Unison 9060040-1G 

Uses:

• Marine Propulsion Gas Turbines Provides high voltage starting power for aeroderivative gas turbines (such as those used in LM2500 series applications) on navy vessels and commercial ships.
• Land-Based Power Generation: Used in gas turbine power plants for peak-load operation to enable reliable automated starting sequences.
• Industrial Process Boilers: Enables clean light-off sequences in heavy crude oil, heavy distillates and gas-fired commercial boilers.
• Offshore Oil & Gas Platforms: Primary ignition source for co-generation sets and mechanical drive turbines in aggressive marine microclimates.

System Compatibility

• Ignition Leads: Compatible with Unison braided stainless steel high-tension ignition leads featuring explosion-proof fittings at the exciter end.
• Igniter Plugs: Matches standard SAE ARP670 Type 5F high-energy surface-gap igniter plugs.
• Turbine Platforms: Designed for integration alongside GE LM2500, Rolls-Royce Allison 501, and similar industrial/marine gas turbine control skids.

Chief Engineer’s Field Notice:

“When installing the Unison 9060040-1G inside a turbine enclosure, remember that this component is completely non-repairable due to its solid-state epoxy encapsulation. If the diagnostic relay triggers continuously, do not attempt to crack open the housing. Always verify the integrity of the high-tension leads and the surface-gap igniter plugs first. Over 70% of apparent exciter failures on marine vessels are actually caused by moisture contamination or carbon-fouling at the ARP670 Type 5F plug tip, which causes a short circuit that prevents the exciter’s output capacitor from building up voltage.

FAQs:

Q1: Can I run the Unison 9060040-1G on a 115VAC power supply?

A: Yes, but it requires changing the physical configuration inside the unit. The exciter is built to handle both 115VAC and 230VAC inputs. To switch input configurations, you must remove the gasketed top cover and re-position the two internal jumpers on the input terminal strip as detailed in the technical manual.

Q2: Is this ignition exciter field-repairable if it stops sparking?

A: No. The internal electronic components are fully encased in a solid epoxy potting compound to protect them against industrial vibrations and moisture. Once a component fails internally, the entire module must be replaced.

Q3: What does a “100VA” rating mean for this equipment?

A: The 100VA rating represents the apparent electrical power consumed by the exciter from the AC line during its operational duty cycle. This high power capacity is required to charge the internal storage capacitors rapidly enough to discharge up to 20,000 Volts at the igniter tip once per second.
