BENDER Isolated Power Panels

BENDER Isolated Power Panels

Introduction

BENDER Isolated Power Panels are designed to provide isolated power to electrical systems in operating rooms and other critical areas. Designed in strict compliance with UL 1047, UL 1022, and UL 50, BENDER isolated power panels offer the most up-to-date technology for all isolated power distribution requirements.

Standard Features

Standard isolation power panels typically include:

• Single-phase isolation transformer

• BENDER LIM2010 Line Isolation Monitor (LIM)

• Reference ground bus

• Primary circuit breaker

• Branch circuit breakers (Qty. 8 standard, field-convertable up to 16)

Additional Features

Additional features available include:

• Provision(s) for receptacles and/or ground jacks

• Circuit control via PLC

• Integrated Fault Location

• Transformer Load Monitoring

Refer to the following pages for more information on these options.

Backbox

All backboxes are fabricated from minimum 14GA galvanized steel. Surface mounted enclosures are finished with a coat of hospital ivory baked enamel or equivalent.

Front Trim

Manufactured from minimum 14GA type 304 stainless steel with #4 brushed finish, the front trim contains a door with hidden hinges and a flush mounted key lock covering the loadcenter. A flush mounted front trim extends 1“ on all sides of the backbox. For surface-mounted panel boards, the front trim has the same dimensions as the enclosure.

Isolation Transformer

Isolation transformers are available with various primary and secondary single-phase voltages. See ordering information for available primary and secondary voltages.

Line Isolation Monitor

The BENDER LIM2010 series Line Isolation Monitor provides both digital and analog displays. The LIM is available with readouts and response values of 2 mA or 5 mA. The LIM2010 utilizes a unique measuring principle and is capable of detecting all combinations of capacitive and resistive faults, including balanced, unbalanced, and hybrid faults. A self-test and self-calibration function is included.

The LIM2010 can monitor for additional alarms, including over- and undervoltage, load monitoring, over-temperature, and more. The LIM2010 may be combined with an installed BENDER EDS series module to create a ground fault location system. For more information, refer to the LIM2010 technical bulletin (document number NAE2022010).

Loadcenter

The loadcenter is an integral part of isolated power panels. Included is a primary circuit breaker which provides protection for the isolation transformer. All isolated power panels may be configured with either plug-in (snap-in) or bolt-on branch circuit breakers.

Features

• Power Distribution: Loadcenter available for either plug-in and bolt-on circuit breakers

• Mounting: Available for flush- or surfacemounted applications

• Advanced technology: The LIM2010 line isolation monitor features self-testing, self-calibration, and a wide variety of alarms including voltage, overload, and overtemperature monitoring

• Outlets: Optional arrangement of receptacles and/or ground jacks

• Controller: Optional combination of PLC and remote / local controls for up to 12 x-ray / laser receptacles

• Standards: Listed to UL 1047, the standard for isolated power system equipment

• Warranty: Industry-first 5 year warranty

Isolated Power Panels with Receptacles and Ground Jacks

BENDER isolated power panels may have provisions for hospital grade power receptacles and hospital grade ground jacks. The hospital grade power receptacles are available in either straight-blade (single or duplex), or twist-to-lock style. Each section can accommodate either one duplex or single power receptacle and one ground jack, or two ground jacks.

BENDER type HGC hospital grade ground cords are recommended for use with this panel configuration (see accessories).

Isolated Power Panels for X-Ray / Laser Equipment

BENDER isolated power panels may also be configured to feed x-ray and laser receptacles at intervals up to 60 A (within the power rating of the panel). The panel is comprised of a power section and a control section. A single panel can supply power for up to twelve (12) circuits. Receptacle modules may be configured with an “in-use“ lamp as well as a LIM remote indicator. The access door to the remote power receptacle may also be equipped with a limit switch used to lock out power to other receptacles connected to the panel.

Programmable Logic Controller (PLC)

The PLC, built into the panel, controls which circuits are available. The PLC control logic is configured to a particular system‘s requirements. Control wiring from push-buttons, door switches, etc. are permanently wired into the input section. Signals or contact closures from the output section may be used to actuate contactors and to apply power to the circuit. The PLC determines how the outputs respond.

BENDER type XRM receptacle modules are recommended for use with this panel configuration (see accessories).

Advantages:

• Ground fault location while the system remains online

• Fast location of faults

• Reduced maintenance costs

• Indication of faulty circuit shown on LCD displays at both the location device and remote indicators
