Mounting
The Axon DTH1620 can be mounted in any orientation with a flat surface that meets the dimensional requirements described under
“Dimensions” on page 11, is not exposed to rain, condensing humidity, excessive heat or cold, and is strong enough to hold the
amplifier, weighing 2 lb, 6 oz, during the intended operational scenarios and shall not block any ventilation holes. In addition, the
mounting location must have enough space to allow cable connections without stressing the connections,
1. Use the dimensions to locate and mark four spots on the mounting surface.
2. If necessary, drill four holes at the marked spots. The drill must be smaller than 0.177 in ches (4.49 mm). and the appropriate size
for the selected mounting hardware.
3. Use appropriate hardware for the mounting-surface material to secure the amplifier in the selected location.
4. Connect and secure the cables to allow for appropriate stress relief.
Selecting a Power Supply for Your Installation
The DTH1620 amplifier draws about 15 W when idle. For operational head room, use 20 W as the idle power. When all channels have
equal power, a safe formula for computing the required current capability of the power supply is:
Is = ((Pc*Nc*Eff)+Pi)/Vs
Where:
Is = Required power supply current capability
Pc = Power per channel (maximum of 20 W per channel)
Nc = Number of channels (maximum of 16)
Eff = Efficiency factor = 1.25 (80%)
Pi = Idle power of amplifier (20 W)
Vs = Supply voltage (24 VDC)
Example: We want all 16 channels to be simultaneously 5W capable.
Is = ((5 W * 16 channels * 1.25 efficient factor) + 20W ) / 24V
Is = ((5*16*1.25)+20)/24
Is = 5A
If all channels have different power output requirements then simply add the output power for all channels.
Is = ((Sp * Eff ) + Pi ) / Vs
Sp = Sum of Power for all channels i.e. (P1 + P2 + P3 + … P16)
