Answer

Power supply options for the Attero Tech DTH1620 can vary based on the intended application and system specifications.

The information below will help in selecting the appropriate power supply for your installation.

The DTH1620 network 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

• 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)
