Introduction
This manual provides instructions for the installation, operation, and maintenance of the Altronix OLS120 Power Supply/Charger. The OLS120 is designed to provide regulated 12VDC or 24VDC power at 4 amps, with integrated AC and battery monitoring capabilities, utilizing a 115VAC input.
Important Safety Instructions
- Installation and servicing should only be performed by qualified service personnel.
- To reduce the risk of electric shock, disconnect AC power before servicing.
- Ensure proper ventilation to prevent overheating.
- Do not expose the unit to rain or moisture.
- Use only recommended battery types for backup power.
Product Overview
The Altronix OLS120 is a robust power supply/charger unit engineered for reliable performance in various applications requiring stable DC power and battery backup.
Key Features
- Selectable 12VDC or 24VDC output.
- 4 amp continuous supply current.
- Integrated AC and battery monitoring.
- 115VAC input for power.
Component Identification
This image displays the Altronix OLS120 circuit board, highlighting various components essential for its operation. Familiarize yourself with these components before installation.
Key Components:
- Voltage Selector Switch: Located at the top right, labeled "OFF 24VDC ON 12VDC". This switch allows selection between 12VDC and 24VDC output.
- AC Input Terminals: Positioned at the bottom left, marked for 115VAC input connections.
- DC Output Terminals: Located at the bottom right, these terminals are for connecting devices that require 12VDC or 24VDC power.
- Battery Terminals: Found at the bottom right, near the PTCs, for connecting backup batteries.
- AC Fail Indicator (LED): An LED near the "AC FAL" label, which illuminates upon loss of AC power.
- Low Battery Indicator (LED): An LED near the "LOW BAT" label, indicating a low battery condition.
- Transformer: A central component, often labeled with part numbers like "P POL-30030", responsible for stepping down the AC voltage.
- Capacitors: Large cylindrical components (e.g., "C2", "C29A") used for filtering and energy storage.
- Fuses/PTCs: Overcurrent protection devices (e.g., "PTC1", "PTC2") to safeguard the circuit.
Setup and Installation
Step 1: Mounting
Securely mount the OLS120 in a suitable enclosure or location, ensuring adequate ventilation to prevent heat buildup.
Step 2: Voltage Selection
Locate the voltage selector switch (labeled "OFF 24VDC ON 12VDC") on the circuit board. Set the switch to the desired output voltage (12VDC or 24VDC) before connecting any power.
Step 3: AC Power Connection
Connect the 115VAC input power to the designated AC input terminals. Ensure proper polarity and secure connections. Refer to local electrical codes for wiring practices.
Step 4: DC Output Connection
Connect your devices requiring DC power to the DC output terminals. Observe correct polarity to prevent damage to the connected equipment.
Step 5: Battery Connection (Optional)
For battery backup functionality, connect a suitable rechargeable battery to the battery terminals. Ensure correct polarity. The OLS120 will charge the battery and automatically switch to battery power upon AC failure.
Operation
Powering On
Once all connections are secure and verified, apply 115VAC power to the unit. The unit will power on and begin providing regulated DC output.
Status Indicators
- AC Fail (LED): This indicator illuminates when the AC input power is lost, signaling that the unit is operating on battery backup (if connected).
- Low Bat (LED): This indicator illuminates when the connected battery voltage drops below a pre-set threshold, indicating that the battery requires charging or replacement.
Maintenance
General Care
Keep the unit clean and free from dust accumulation. Ensure that all ventilation openings are not obstructed to maintain optimal operating temperature.
Battery Maintenance
If a backup battery is used, periodically check its condition and charge level. Replace the battery as recommended by the battery manufacturer or when its performance degrades.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No DC Output | No AC input power | Check AC power source and connections. |
| No DC Output | Incorrect voltage selection | Verify voltage selector switch is set correctly (12VDC or 24VDC). |
| AC Fail LED On | Loss of AC power | Restore AC power. |
| Low Bat LED On | Discharged or faulty battery | Check battery charge and condition; replace if necessary. |
| Intermittent Output | Loose connections | Secure all wiring connections. |
