Product Release: SecurBox – Complete Power & Distribution Cabinet for Security Installations

Powerbox has introduced SecurBox to address the practical requirements of the electronic security sector in New Zealand. These wall-mounted, pre-wired cabinets combine regulated DC power, battery charging, and fused distribution into a single, ready-to-install enclosure. This integrated design helps security professionals save time on-site, minimise wiring complexity, and maintain a consistent installation standard across projects.

Manufactured by Powerbox to meet local compliance requirements, SecurBox provides a robust, compliant, and time-efficient solution tailored to the realities of New Zealand security installations.

Designed with Security Professionals in Mind

Feedback from experienced installers and system integrators has shaped the SecurBox concept. Whether used for standalone access control or as part of a multi-site deployment, the cabinets are built to remove common power system installation headaches and deliver a reliable, field-ready outcome.

Key Features and Options

Factory-Assembled & Pre-Wired

Every unit comes with the charger, PDM, voltmeter, tamper switches, and mains lead pre-installed and interconnected, reducing set-up time.

Fire Trip Capability

Eight-way configurations offer glass fuses with outputs selectable for either standard power or fire trip operation – ideal for projects involving life safety integration.

Resettable PTC Fuse Models

Compact PDM variants with 10 or 20 outputs feature self-healing fuses for easier servicing and ongoing load protection.

Diagnostics & Status Feedback

LEDs and Form-C relay contacts indicate mains status, battery health, and fuse condition for straightforward system monitoring.

Dual Tamper Protection

Both the cover and the chassis are monitored to detect unauthorised access.

Installer-Friendly Layout

Includes rear and side cable entry points, provision for two GPO cut-outs, and passive ventilation for better integration on-site.

¹ Glass fuses are standard 5×20mm field-replaceable types and can be swapped to suit application current ratings.

² PTC (polymer resettable) fuses provide automatic recovery after fault clearance and are rated for nominal hold current at 25°C. Trip and reset characteristics vary with ambient temperature and load profile.

³ Each fused output can be individually configured as fire trip or standard power. Fire trip mode de-energises the output when the monitored fire relay input is activated (12–24Vdc coil or dry contact).

⁴ All models are internally pre-wired from battery charger to power distribution module and battery terminals. Battery must be supplied separately and connected on site.

Built Around the PBB2S MKII Charger Platform

At the heart of each SecurBox is the Powerbox PBB2S MKII DC-UPS battery charger. This unit delivers a regulated 12Vdc or 24Vdc output with integrated battery backup, ensuring uninterrupted operation for access control, CCTV, and alarm systems.

All models used within the SecurBox series are registered under the Electrical Equipment Safety System (EESS) and comply with both Australian and New Zealand standards for in-scope devices, including:

• AS/NZS 61558.2.16 – General-purpose power supply safety

• AS/NZS 62368.1 – Safety for ICT and AV equipment

• CISPR 32 Class B – EMC compliance for commercial environments

EESS Registration Number: E2025004894 – streamlining safety documentation for security projects.

Each charger also incorporates LED fault indication and relay outputs to report mains failure, battery status, and fuse faults – supporting effective monitoring within control systems.

Available Across New Zealand

The SecurBox series is now available through Powerbox New Zealand and approved security distributors nationwide. Built to meet the needs of installers, consultants, and project managers, SecurBox delivers a fully integrated DC power and distribution platform – ready for immediate deployment from day one.
