APC SRT5KRMTF APC Smart-UPS Step-Down Transformer, 5kVA, rackmount, 2U, 12x NEMA 5-20R outlets SRT5KRMTF

Data Sheet: APC Smart-UPS 5kVA 2U Rackmount Step-Down Transformer (SRT5KRMTF)

The APC SRT5KRMTF is an enterprise-class, heavy-duty 2U rackmount step-down power distribution module engineered to convert high-voltage $208\text{V}$ AC power into low-voltage $120\text{V}$ AC power. Functioning as a high-capacity isolation and matching infrastructure unit, this 5kVA subsystem manages a total continuous load current of 24A. It is explicitly designed to expand the outlet profile of high-voltage multi-kilowatt UPS engines, enabling them to simultaneously power low-voltage hardware, legacy IT systems, network infrastructure, and high-density computing accessories within a centralized 19-inch equipment cabinet.

Equipment Variants for SKYRS Pakistan

SKYRS supervises regional procurement pipelines, electrical phase balancing, and customized input/output integration arrays across Pakistan for this heavy-duty 5kVA transformer series:

• SRT5KRMTF: The standard enterprise 2U rackmount package detailed here. It features a factory attached NEMA L6-30P input plug and 12 breaker-protected NEMA 5-20R straight-blade low-voltage outputs. Sourced by SKYRS to bridge localized high-voltage lines down to low-voltage equipment loads.

• AP9626: A specialized legacy 5000VA step-down variant utilizing an identical NEMA L6-30P input line paired with twelve 5-20R straight-blade outputs, maintained under custom storage supply metrics for retrofitting existing systems.

• AP9627: A twist-lock variant alternative built within the identical 5kVA footprint, replacing straight-blade outputs with four (4) NEMA L5-20R twist-lock low-voltage sockets to prevent accidental cord disconnection under seismic or industrial vibrations.

Deployment, Installation, and Configuration

Grid Integration and Phase Management Engineering

• Mains Phase Realignment Mapping: The SRT5KRMTF requires a stable high-voltage single-phase 208V AC feed via its native NEMA L6-30P input cord. Because Pakistan’s national grid operates on a standard single-phase 230V framework (Phase + Neutral), SKYRS electrical engineers design, test, and assemble specialized upstream isolation step-down or matching panels. This steps the local 230V utility feed down to a stable, continuous 208V feed, safely energizing the transformer’s input loop.

• Thermal Flow Protection: Reserve a dedicated 2U horizontal gap in a standard 19-inch server cabinet. Keep a minimum clear perimeter of 100 mm at the rear exhaust pane to prevent thermal pooling and keep internal temperatures below 40°C.

• Structural Mass Support Placement: Because this transformer incorporates a dense copper/magnetic core configuration weighing 43.09 kg, it introduces massive concentrated structural stress. SKYRS structural deployment protocols dictate mounting the transformer directly adjacent to—preferably one slot above—the main companion UPS module near the base of the rack to maintain a low center of gravity.

Physical Installation Sequence

1. Cabinet Support Rail Attachment: Mount the heavy-duty adjustable 4-post rack rail installation kit into the designated 2U slot of the equipment cabinet.

2. Chassis Seating: Lift and slide the 43.09 kg transformer framework along the rail channels. Bolt the front mounting brackets to the rack’s vertical rails using standard M6 cage nuts.

3. Inter-Module Power Routing: Firmly insert the transformer’s integrated NEMA L6-30P twist-lock input cord directly into the 208V AC output socket of the host UPS or matching utility interface provided by SKYRS, turning the plug clockwise until it snaps locked.

4. Load Management Distribution: Group your critical low-voltage hardware power cables across the four distinct 15A breaker-protected branches on the rear of the module. Distribute the active current draw equally among the branches to prevent minor load spikes from causing nuisance circuit breaker trips.

System Verification Protocol

1. Circuit Breaker Initialization: Verify that all four branch circuit breaker switches on the rear panel are toggled to the “On” position.

2. Output Voltage Diagnostics: Before hot-plugging critical equipment, SKYRS field technicians perform manual true-RMS digital multimeter diagnostics across the NEMA 5-20R receptacles to verify nominal $120\text{V}\pm 3\%$ voltage stability.

3. UPS Monitoring Integration: Access the local LCD console or the Network Management Card interface of your host UPS. Check that the added load current (measured in Amps/Watts through the 208V feed line) registers correctly, ensuring your runtime forecasting and emergency load-shedding scripts match the physical installation profile.
