Tripp Lite PDUMH20ATNET Specifications

    Tripp Lite PDU Switched ATS 120V 20A 5-15/20R 16 Outlet L5-20P Horizontal


    Rear View
    Tripp Lite's 120V 20A metered PDU system with Automatic Transfer Switching (ATS) is a 16 outlet PDU with a digital display to indicate total PDU power consumption in amps. Outlets are sequentially turned-on at 250 millisecond intervals when the PDU is first energized from an unpowered state to prevent inrush-related equipment interaction on startup. Installed web/network monitoring card enables remote power monitoring and control. Remotely displays status of input power, load capacity, and outlet power status via secure network or web browswer interface. Offers individual outlet control to power on, off, or cycle AC output to regain control of locked-up servers and other network devices. Load ramping and shedding provides automatic power management. Supports notification and logging of input power status, event notification, output power and load conditions. Supports 1U rackmount installation in a 2 or 4 post racks. Included are 16 NEMA 5-15/20R outlets, and optional-use dual cords for auto- transfer switching (ATS) options. Each input plug supports 5-20P and L5-20P input.

    Optional integrated ATS is available for use when two separately derived input power sources are available. The attached power cord serves as the primary AC input cable, while the included detachable power cord serves as the optional-use secondary AC input connection. The PDU system passes the primary input power through to connected equipment whenever line voltage and frequency levels are normal. If the primary input source goes outside of these tolerances or fails altogether, the ATS will automatically switch all PDU output to the secondary line sourced input power (when available) to maintain continuous operation of connected loads without reboots or service interruptions. Once the primary power source is restored, the PDU will automatically switch back to primary sourced input power. The dual input cabling can be configured for UPS maintenance bypass of standard UPS systems or to create a redundant dual-UPS power source for a critical, single-corded network device. Front AC input LED's show what input AC source is being utilized by the PDU.

    Tripp Lite Switched ATS / Auto Transfer Switch provides a redundant power option for single-corded network devices. Dual input cords support separate connection to PRIMARY and SECONDARY power sources. The ATS will normally maintain continuous output to all outlets as derived from the primary input cable. If the primary power source becomes unstable or fails altogether, the ATS will switch over to the secondary power source until the primary input is restored and stable. The built-in Java-free HTML5-based LX Platform network interface enables full remote access for PDU status monitoring and email notifications via secure web browser, SNMP, telnet or SSH. It supports 10/100 Mbps auto-sensing for optimum communication with an Ethernet network. Optional EnviroSense2 modules (sold separately) provide a variety of environmental monitoring capabilities. Protocols supported include IPv4, IPv6, HTTP, HTTPS, SMTP, SNMPv1, SNMPv2, SNMPv3, telnet, SSH, FTP, DHCP, BOOTP and NTP. Switched PDU features include individually controllable output receptacles and built-in network interface. Super-fast switchover between primary and secondary power sources occurs within milliseconds. ATS functionality is supported by any two compatible AC power sources, regardless of phase angle, to support a variety of advanced redundant power networking applications. Enables fault tolerant hot-swappable UPS protection when used with a single UPS and fully redundant UPS protection when each cord is connected to a separate UPS system. In a two-UPS environment, the primary input cable must be supported by a full time sine wave UPS with zero transfer time. Tripp Lite SmartOnline series is highly recommended for use as the primary UPS in a two-UPS application. ATS configurations utilizing separate mains circuits, backup generators and even separate utility power grid feeds are fully supported. On-board ATS processor constantly evaluates power quality on both input sources to prevent transfer to the secondary source when unavailable or of lower quality than the primary source. Front input LED's display primary or secondary power availability.
