Deep Sea Electronics (DSE) controllers are the control brain of a generator set — handling engine start/stop, monitoring, protection, and, on AMF models, automatic mains failure switching. Getting the right controller model matters more than with most parts, since a DSE controller has to match your generator’s control panel wiring and the features your installation actually needs. This guide covers the difference between DSE’s model ranges, the accessories that go with them, and how to identify the right one for your setup.
Autostart vs. AMF — what’s the difference?
DSE controllers split into two main categories:
- Autostart controllers — start and stop the generator automatically (on a schedule, a remote signal, or a mains-failure input from elsewhere), and monitor engine parameters, but don’t include the transfer switching logic themselves.
- AMF (Automatic Mains Failure) controllers — include everything an autostart controller does, plus built-in logic to detect a mains power failure, start the generator, and manage the transfer switch to move the load onto generator power automatically, then back to mains once it’s restored.
If your generator needs to take over automatically when utility power drops, you need an AMF model; if starting is handled some other way (manually, or by an external transfer switch), an Autostart controller is the right match.
Deep Sea controller models
- DSE8610 MKII Auto Start
- DSE7420 MKII AMF
- DSE7320 MKII AMF
- DSE7310 MKII Autostart
- DSE6120 MKIII AMF
- DSE6110 MKIII Autostart
- DSE3110
Not sure which one you need? Our DSE7320 MKII vs DSE8610 MKII guide compares the DSE6110 MKIII, DSE7320 MKII, DSE8610 MKII and DSE8660 MKII side by side.
As a rough guide, the higher the model number within a series, the more features included (AMF logic, additional monitored parameters, expanded I/O) — but always confirm against your existing panel or generator manual, since the exact model determines both the wiring and the front-panel configuration.
Accessories & battery chargers
A DSE installation typically also needs a battery charger to keep the starting battery topped up between runs, plus any panel accessories your installation calls for:
- DSE890 Accessory
- Battery Charger BC9702-002, 12V 5Amp
- Battery Charger BC9701-005, 24V 5Amp
- Battery Charger BC9150-004, 12V 5Amp
- Battery Charger BC9130-009, 12V 5Amp
Match the battery charger voltage (12V or 24V) to your generator’s starting battery system — this is the most common ordering mistake.

How to identify the right controller for your generator
- Check your existing controller’s model number. It’s printed on the front panel or the rear label — the fastest way to confirm an exact replacement.
- Decide whether you need AMF or Autostart. If the generator needs to detect a mains failure and switch over on its own, you need an AMF model.
- Match your battery charger voltage. Confirm whether your starting battery system is 12V or 24V before ordering a charger.
- When in doubt, ask before ordering. Send us your generator’s make and model, or a photo of your existing panel, and we’ll confirm the correct controller before you buy.
Genuine parts vs. aftermarket
Generator controllers are safety-critical electronics — an incorrectly matched AMF controller can fail to transfer load correctly during a real mains outage. This is an area where confirming the exact genuine Deep Sea Electronics model for your panel matters far more than any cost saving from a substitute part.
FAQ
What’s the difference between a Deep Sea AMF controller and an Autostart controller?
An AMF (Automatic Mains Failure) controller detects a mains power failure and automatically starts the generator and switches the load over, then back once mains power returns. An Autostart controller starts and stops the generator and monitors it, but doesn’t include that automatic transfer-switching logic.
How do I know which Deep Sea controller model I need?
Check the model number printed on your existing controller’s front panel or rear label. If you’re replacing a controller for the first time, send us your generator’s make and model and we’ll confirm the correct match.
Do I need a 12V or 24V battery charger?
That depends on your generator’s starting battery system — check the voltage of your existing battery bank before ordering, since 12V and 24V chargers aren’t interchangeable.
What does the DSE890 accessory do?
It’s a Deep Sea Electronics panel accessory used alongside compatible controller models — check compatibility against your specific controller model before ordering.
