Motorola SS-18MT Power Switching Power Supply

Motorola SS-18MT Power Switching Power Supply (marketed as Astron SS-18MT/XPR5) is a radio‑specific, switch‑mode DC supply designed to feed MOTOTRBO equipment. It delivers 13.8 VDC at up to 18 A, a configuration commonly used with MotoTRBO XPR5000 and related radios in desktop, table‑top installations. The unit accepts dual input voltages—110–120 VAC or 220–240 VAC—making it suitable for international deployments. In catalogs and retailer listings, the SS-18MT/XPR5 is described as a radio‑specific power source for MotoTRBO systems, with compatibility noted for XPR4000 and XPR5000 series, DM4000, and XPR5000e variants. As a compact, switching supply, it provides a dedicated 13.8 V supply to support radio operation and accessory loads in Motorola/MOTOTRBO base configurations.
