Leistungsmesser relays offer four voltage variants for flexible power measurement and control - Voltage variants: SLA 05VDC SL A (5V), SLA 09VDC SL A (9V), SLA 12VDC SL A (12V), SLA 24VDC SL A (24V) - Current rating: each relay supports up to 30 A - Configuration: 4-pole design for switching four contacts with a single actuation - Quantity: includes five pieces of the 5V variant - Applications: suitable for power related measurement or control tasks that require different voltage rails and reliable high current switching Key benefits - Multi-rail capability: switch four circuits at once across different voltage levels with one relay unit - High current performance: 30 A capacity supports demanding DC loads - Versatile voltage compatibility: four voltage options accommodate a range of power measurement and control needs - Consistent performance: same 4-pole architecture and current rating across variants Practical use scenarios - Power measurement setup that requires switching between 5, 9, 12, or 24 V rails while monitoring current - Control panel for DC systems where multiple loads must be routed or isolated with a single relay actuation - Development or testing rigs that simulate multi-rail circuits and switch up to 30 A per contact
