AstralPool Salt Chlorinator Cell Voltage, Current & Chlorine Output
The following table provides electrical output specifications for selected AstralPool salt chlorinators, including the VX Series, E-Series and Viron eQuilibrium.
These specifications are provided as a technical reference for qualified technicians diagnosing chlorinator cells, power supplies and control systems. Note that these figures are subject to change without notice.
| Series | Model | Chlorine Output | Rated DC Voltage | Rated / Nominal DC Current |
|---|---|---|---|---|
| VX | VX6 S/T | 15 g/h | 16.5 V | 6.3 A |
| VX | VX7 S/T | 25 g/h | 16.5 V | 8.5 A |
| VX | VX9 S/T | 30 g/h | 20.5 V | 8.5 A |
| VX | VX11 S/T | 42 g/h | 24 V | 8.5 A |
| VX | VX13 S/T | 50 g/h | 28.5 V | 8.5 A |
| E-Series | E25 | 25 g/h | Not published | 4.4 A |
| E-Series | E35 | 35 g/h | Not published | 5.8 A |
| Viron eQuilibrium | EQ18 / Compact | 18 g/h | Not published | 3.6 A |
| Viron eQuilibrium | EQ25 / Mid | 25 g/h | Not published | 5.0 A |
| Viron eQuilibrium | EQ35 / Large | 35 g/h | Not published | 7.2 A |
Specifications: The VX voltage and current figures are published DC controller output ratings from Australian electrical certification records dated 2013. E-Series and Viron eQuilibrium current figures are nominal outputs published in AstralPool installation manuals. Chlorine production is expressed in grams per hour (g/h). S = without timer; T = with timer. Specifications may vary between model versions, particularly special variants. Confirm the exact model and rating plate before undertaking electrical diagnostics.
Important Information for Electrical Diagnostics
The voltage and current figures above are manufacturer or certification reference ratings. They should not be interpreted as maximum permissible electrical values or guaranteed operating measurements.
- DC Voltage: The voltage measured across a connected chlorinator cell may vary depending on the controller design, water salinity, temperature, electrode condition and electrical load.
- DC Current: Current flowing through the cell is directly related to the electrolysis process. Low current may indicate insufficient salinity, electrode deterioration, scale build-up, poor connections or a controller fault.
- Polarity Reversal: Self-cleaning chlorinators periodically reverse the polarity of the cell. This can change the polarity of voltage readings and interrupt production temporarily.
- Output Settings: Reduced chlorine output settings, programmed operating periods and automatic control functions can affect when and how the cell is energised.
- Testing Under Load: A voltage reading with the cell disconnected does not confirm that the controller can deliver its rated current. Suitable diagnostic measurements must account for the connected cell and the controller's operating state.
- Cell Condition: Voltage and current readings alone cannot conclusively establish whether a chlorinator cell or control board is faulty.
Electrical Safety & Technical Disclaimer
WARNING: ELECTRICAL SAFETY
All electrical work, including electrical testing, fault diagnosis, installation, servicing and repairs, must be carried out by an appropriately qualified and licensed electrical professional in accordance with applicable Australian electrical safety legislation, AS/NZS 3000 and manufacturer requirements.
Chlorinator control units contain mains-voltage electrical components capable of causing serious injury or death. Electrical testing under live conditions must only be undertaken by appropriately qualified persons using suitable equipment and safe work procedures.
The information on this page is provided for general technical reference only. It does not constitute a diagnostic procedure, repair instruction or authorisation to perform electrical work.
While reasonable care has been taken to reproduce published specifications, Heater & Spa Parts cannot guarantee that the figures apply to every production version or replacement controller. Always refer to the rating plate and official manufacturer documentation for the exact equipment being tested.
Do not use these reference values alone to determine whether a chlorinator cell or controller is serviceable, defective or suitable for replacement.
