Bosch BO-48C18133A Power Supply 18V AC – 18 V AC Power Supply (Approx. 1.33 A)

SKU: BO-48C18133A
Description

The Bosch BO-48C18133A is an 18 V AC power supply for Bosch Solution alarm panels and other systems that need an 18 V AC input. It takes 240 V AC mains and delivers approximately 1.33 A of AC output through pre-attached bare-wire leads, making it a straightforward replacement or spare transformer for a Solution control panel. Because it outputs AC (not DC), it must match panels designed for an 18 V AC supply.

§ 01Overview

What the BO-48C18133A is

The Bosch BO-48C18133A is the mains transformer that powers a Bosch Solution alarm panel. It converts 240 V AC mains down to an 18 V AC output of about 1.33 A, which is the supply the Solution control boards are designed to run from, with the panel then charging its backup battery and powering keypads and detectors from that feed.

It is a practical part for two jobs: completing a new install where you need the panel's plug pack, and replacing an ageing or failed transformer on an existing system. Output is through pre-attached bare-wire leads that terminate straight to the panel's AC input terminals, and the compact body mounts inside or beside the alarm enclosure.

Two honest notes. This unit outputs AC, not DC - it is only for panels that specify an 18 V AC supply, so check your panel's requirement before fitting it. And because it is mains-connected, it must be installed by a licensed person: isolate the mains, terminate the AC leads to the correct panel terminals, and mount it within an approved enclosure. It is genuine Bosch stock with local 3-year warranty.

§ 06Setup

Installation & setup

01

What's in the box

One BO-48C18133A 18 V AC power supply with pre-attached bare-wire output leads. The control panel, enclosure and backup battery are not included.

02

Installation requirements

To be installed by a licensed person. Isolate the 240 V AC mains, confirm the panel requires an 18 V AC supply, terminate the bare-wire AC output leads to the correct panel input terminals, and mount the unit within an approved enclosure. Fit the panel's separate 12 V backup battery so the system rides through a mains failure.

§ 07Questions

Frequently asked about the BO-48C18133A

Q.01

Is this an AC or a DC power supply?
It outputs 18 V AC, not DC. Many Bosch Solution panels are designed to run from an 18 V AC supply and charge their own backup battery from it, so this transformer matches those panels. Do not use it where a DC plug pack is required.
Q.02

Which Bosch panels does it suit?
It is commonly used with Bosch Solution series alarm control panels that require an 18 V AC input of around 1.3 A, including as the plug pack for a Solution 3000 board. Always confirm your panel's stated supply requirement before fitting it.
Q.03

Can I use it as a replacement transformer?
Yes. It is well suited as a replacement or service spare for an ageing or failed 18 V AC transformer on a Bosch Solution system, as well as for new installations.
Q.04

How does it connect to the panel?
It has pre-attached bare-wire output leads that terminate directly to the panel's AC input terminals. There is no plug - it is wired in as part of the alarm installation.
Q.05

Does it have a backup battery?
No. It is the mains transformer only. The panel uses a separate 12 V sealed lead-acid battery for backup during a power failure, which is purchased separately.
Q.06

Can I install it myself?
Because it connects to 240 V AC mains and forms part of an alarm system, it should be installed by a licensed person. Isolate the mains first, terminate the AC leads to the correct panel terminals, and mount it within an approved enclosure.
