Protection All Cascade Audio Engineering APS Power Supplies feature temperature, overcurrent and reverse-polarity protection circuitry. They will provide stable regulated DC output voltage (13.6V or 14.2V, relative to jumper connection - The APS-100 is 13.4V only) regardless of the load by varying output current to compensate. AC input protection against damaging spikes of up to 190VAC and brown-out input protection are also provided. All APS Power Supplies feature an automatic, thermally trigge

Your new APS Power Supply can be used with or without an additional bat- tery. Use of a battery connected in parallel with your APS power supply will greatly increase the current available for transients. For installations where use of a battery is not possible, capacitors may be used. Vehicle Installation Two methods of vehicle installation are commonly used. One is to mount the positive and negative battery cables to the vehicle and to place the power supply under the vehicle when necessary. E

Cut the positive and negative cables that will go from the power supply to the load (battery, display board, distribution blocks, etc.) to the desired length. Always use the proper sized cable based on the amperage of the power supply and the distance between the power supply and the load (Please refer to the chart at the end of this manual). Allow for proper routing of the cables. Strip approx. 1” of insulation from one end of each cable. Insert the stripped end of the positive (red) cable into

Connecting Multiple APS Power Supplies APS power supplies may be connected in parallel to increase their current capability. There are a few important steps to follow: 1. APS power supplies must only be connected to other APS units of the same model. Example: An APS-55 can ONLY be connected to other APS-55 power sup- plies. Failure to comply with this step will void your warranty. 2. APS power supplies must be connected in parallel (Positive to positive and negative to negative). 3. It is possib

Fuses Your APS Power Supply is protected against reverse polarity. If the battery or the APS unit is hooked up incorrectly, the fuse on the end panel will blow and can easily be replaced. When replacing fuses, always use the same size AGC style fuses that came with your power supply. The fuses are located next to the DC output terminals (Refer to the picture below). AC Input Cord All APS Power Supplies must be plugged into a 120V AC outlet. They are not equipped with on/off switches. Do not plug
