Description

APC by Schneider Electric SYH6K6RMT 6kVA Rackmount UPS

Overview

The APC Symmetra RM SYH6K6RMT is a 6000VA (4200W) rack-mountable UPS designed for critical IT environments where continuous, clean power is essential. This double-conversion online unit provides 208V output, ensuring sensitive equipment like servers, network switches, and storage arrays are protected from power fluctuations, outages, and noise. Its N+1 power module redundancy and configurable output voltage make it suitable for demanding enterprise deployments. The SYH6K6RMT is a robust power protection solution for rack-based infrastructure.

Compatibility

This UPS is designed for use with standard 19-inch rack enclosures. It accepts a 208V input via a NEMA L6-30P connector and provides 208V output through two NEMA L6-20R and one NEMA L6-30R receptacle. It is compatible with IT equipment requiring clean sine wave power and tolerates input frequencies of 50/60 Hz. The unit's 8U rack height requires adequate vertical space within the rack.

Installation Notes

Installation requires a qualified electrician to connect the NEMA L6-30P input plug to a compatible 208V circuit. The unit is designed for front mounting, with a preference for lower rack positions to manage weight distribution. The UPS operates within a relative humidity range of 0-95% and an ambient air temperature of 5-45°C (41-113°F). Acoustic levels are rated at 60 dBA. The unit includes 3 pre-installed power modules and 1 empty slot for potential future expansion or replacement.
