Installation / Setup
The PS150 and PS151 power supplies are installed in the RMT150 rack tray by positioning them at the far right side. Before final placement, ensure that the hooks on the rear panel secure the power supply to the tray. Align the LCD and pushbuttons with the front panel holes and secure the power supply with the provided screws. Connect power cables between the transcoders and the power supply, noting that each connector is numbered. The leftmost transcoder is typically connected to socket number 1, continuing sequentially to the right. Ensure the fan cable is connected to the socket on the rear of the supply. Once all connections are made, plug the line cord into a 120 VAC outlet.
Operation
The PS150 and PS151 power supplies are designed to provide power for Drake model SCT1860, SCT2860, SCT3860, and SCT4860 transcoders when mounted in the model RMT150 rack mounting tray. The PS150 can power up to a full tray of 10 SCT1860s, while the PS151 can power a full tray of 10 of any mix of the transcoder models listed. These power supplies also provide an interface between a PC or modem and the transcoders via the RS232 DB9 connectors, allowing for remote programming and monitoring capabilities.
To install the PS150 or PS151, position it at the far right side of the RMT150 rack tray, ensuring the hooks on the rear panel secure the supply in place. Align the LCD and pushbuttons with the front panel holes, and install the provided screws to secure the power supply. Connect the power cables between the transcoders and the power supply, noting that each power output connector is numbered, which helps determine the unit ID of the connected transcoder. Route the power cable for the front mounted fans and plug it into the socket on the rear of the supply. Finally, plug the line cord into a nominal 120 VAC outlet.
For remote control, connect the serial port cable from the PC to the ‘RS232 IN’ connector on the supply. The ‘RS232 OUT’ connector can be used to connect to another PS150/151 or a PS100 for additional transcoders, allowing for a maximum of 7 PS150/151s (70 transcoders max.) to be connected. Up to 63 SCT860s can also be controlled if PS100s are daisy-chained in this connection.

If the power supply fails to turn on, check the AC input connection and verify the fuse is intact. In case of voltage drops or unstable output, inspect all cable connections and ensure the load does not exceed the rated current. Regularly clean the ventilation openings and fan to prevent overheating. If the unit overheats or shuts down unexpectedly, allow it to cool before restarting. For persistent issues, consult the manual or contact qualified service personnel.
Safety Reminder
Always operate the Drake PS-150/PS-151 in a dry, well-ventilated area away from flammable materials. Avoid exposing the unit to moisture or extreme temperatures. Never attempt to open or service the power supply while it is connected to AC power to prevent electric shock. Use only recommended cables and connectors to ensure safe and reliable operation.
